Fractional Horsepower Motors
A fractional-horsepower motor (FHP) is an electric motor with a rated output power of less than (the term 'fractional' indicates less than one unit). There is no defined minimum output, however, it is generally accepted that a motor with a frame size of less than 35mm square can be referred to as a 'micro-motor'. Fractional-horsepower electric motors are exempt from the US Energy Policy Act of 2005 and the new EN 60034-30:2009 ruling of European directive 2005/32/EC concerning the efficiency classes of low-voltage three-phase asynchronous motors. History The earliest commercially successful electric motors date back to the latter part of the 19th century when Nikola Tesla patented his induction motor in 1888. The development of fractional-horsepower motors, however, would not have taken place without the push toward urban, and later, rural electrification, using alternating current. Electrification began in cities around 1900, and Chester Beach, an employee of Hamilton-Beach co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parvalux Motor
Parvalux Electric Motors Ltd is a British manufacturer of fractional horsepower geared electric motors. Based in Wallisdown, Bournemouth in southern England. In December 2018, Parvalux was acquired by maxon motor AG. History The name ‘Parvalux’ derives from the Latin ' parvulus' and 'lux' and means 'young light', alluding to the hopes that founder Leslie J. Clark had for the Romford-based business where he first began selling motor rewinds in 1947. After relocating to Bournemouth in 1957, the company moved from simply re-winding motors to designing and manufacturing complete gear-motor units for industrial applications. Parvalux prospered for forty years through continued expansion of its product offer to cover a broad range of AC/DC electric motors and gearboxes, enabling the business to sell into a diverse range of markets and applications ― all over the world. In 2003, Steven Clark took over as Chief Executive. In 2008 Parvalux acquired rival firm and DC motor applicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servo Motors
A servomotor (or servo motor) is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors. Servomotors are not a specific class of motor, although the term ''servomotor'' is often used to refer to a motor suitable for use in a closed-loop control system. Servomotors are used in applications such as robotics, CNC machinery, and automated manufacturing. Mechanism A servomotor is a closed-loop servomechanism that uses position feedback to control its motion and final position. The input to its control is a signal (either analogue or digital) representing the position commanded for the output shaft. The motor is paired with some type of position encoder to provide position and speed feedback. In the simpl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrolux
Electrolux AB () is a Swedish multinational home appliance manufacturer, headquartered in Stockholm. It is consistently ranked the world's second largest appliance maker by units sold, after Whirlpool.

White Goods
A major appliance, also known as a large domestic appliance or large electric appliance or simply a large appliance, large domestic, or large electric, is a non-portable or semi-portable machine used for routine housekeeping tasks such as cooking, washing laundry, or food preservation. Such appliances are sometimes collectively known as white goods, as the products were traditionally white in colour, although a variety of colours are now available. An appliance is different from a plumbing fixture because it uses electricity or fuel. Major appliances differ from small appliances because they are bigger and not portable. They are often considered fixtures and part of real estate and as such they are often supplied to tenants as part of otherwise unfurnished rental properties. Major appliances may have special electrical connections, connections to gas supplies, or special plumbing and ventilation arrangements that may be permanently connected to the appliance. This limits wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Milliradian
A milliradian ( SI-symbol mrad, sometimes also abbreviated mil) is an SI derived unit for angular measurement which is defined as a thousandth of a radian (0.001 radian). Milliradians are used in adjustment of firearm sights by adjusting the angle of the sight compared to the barrel (up, down, left, or right). Milliradians are also used for comparing shot groupings, or to compare the difficulty of hitting different sized shooting targets at different distances. When using a scope with both mrad adjustment and a reticle with mrad markings (called an "mrad/mrad scope"), the shooter can use the reticle as a ruler to count the number of mrads a shot was off-target, which directly translates to the sight adjustment needed to hit the target with a follow up shot. Optics with mrad markings in the reticle can also be used to make a range estimation of a known size target, or vice versa, to determine a target size if the distance is known, a practice called "milling". Milliradians ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planetary Gear
An epicyclic gear train (also known as a planetary gearset) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates the planet and sun gears mesh so that their pitch circles roll without slip. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear. An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of a fixed, outer gear ring, or ring gear, sometimes called an ''annular gear''. In this case, the curve traced by a point on the pitch circle of the planet is a hypocycloid. The combination of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a ''planetary gear train''.J. J. Uicker, G. R. Pennock and J. E.

Stepper Motors
A stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. ''Stepper'' is short for step-and-repeat camera. Steppers are an essential part of the complex process, called photolithography, which creates millions of microscopic circuit elements on the surface of chips of silicon. These chips form the heart of ICs such as computer processors, memory chips, and many other devices. The stepper emerged in the late 1970s but did not become widespread until the 1980s. This was because it was replacing an earlier technology, the mask aligner. Aligners imaged the entire surface of a wafer at the same time, producing many chips in a single operation. In contrast, the stepper imaged only one chip at a time, and was thus much slower to operate. The stepper eventually displaced the aligner when the relentless forces of Moore's Law demanded that smaller feature sizes be used. Because the stepper imag ...

Soda Fountains
A soda fountain is a device that dispenses carbonated soft drinks, called fountain drinks. They can be found in restaurants, concession stands and other locations such as convenience stores. The device combines flavored syrup or syrup concentrate and carbon dioxide with chilled and purified water to make soft drinks, either manually, or in a vending machine which is essentially an automated soda fountain that is operated using a soda gun. Today, the syrup often is pumped from a special container called a bag-in-box (BiB). Fountain coke is an often confused term normally referring to a handheld dispenser behind a bar or counter that are used in many countries, including Spain, France and the United Kingdom. The term ‘fountain’ helps differentiate from, ‘machine’ cola as the fountain is more easily controlled and offers more flavours. A soda fountain is also referred to as a postmix machine in some markets. Any brand of soft drink that is available as postmix syrup may ...

Electric Motor
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be brushed or brushless, single-phase, two-phase, or three-phase, axial or radial flux, and may be air-cooled or liquid-cooled. Standardized motors pr ...

Milkshake Machine
A milkshake machine or drink mixer is a kind of countertop electric mixer used to make milkshakes, flavored milk, frappés, and other blended beverages. Milkshake machines are generally used in ice cream stores and fast food restaurants, and are not common as domestic appliances, where blenders are typically used instead. Overview A milkshake machine consists of a stand for an electric motor and a removable cup, a "malt cup". The motor is connected to a vertical rod at the bottom of which is an small agitator of wavy metal or plastic. The cup is placed so that the agitator is submerged, and sits on the floor of the stand, or on a small bracket. The malt cup is a flared cup, usually of stainless steel. History Manual, crank-driven milkshake machines were introduced by James Tufts in 1884, under the name Lightning Shaker. The modern top-driven electric milkshake machine was invented by Frederick J. Osius in 1910, and commercialized by his Hamilton Beach company under the nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
