Somfy is a French group of companies founded in 1969, some of the largest manufacturers and suppliers of controllers and drives for entrance gates, garage doors, window blinds and awnings. [1] They also produce other home automation products such as security devices. [ 2 ]
Its products are available for sale in several European countries, such as France, Germany, Spain, Italy, Sweden, Switzerland, and the United Kingdom. The company launched in North America (United States and Canada) in June 2015. [5] [6] [7] In 2016, Somfy acquired MyFox. [8]
A ZQDR-410 traction motor (the large, dark component on the axle with small ventilation holes) A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains.
A repulsion motor is a type of electric motor which runs on alternating current (AC). It was formerly used as a traction motor for electric trains (e.g. SR Class CP and SR Class SL electric multiple units) but has been superseded by other types of motors. [citation needed] Repulsion motors are classified as single phase motors.
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
Agni Lynch motor fitted to an electric motorcycle. The Lynch motor is a unique axial gap permanent magnet brushed DC electric motor. [1] The motor has a pancake-like shape and was invented by Cedric Lynch in 1979, the relevant patent being filed on 18 December 1986.
An industrial electric motor . An electric motor is a 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.
AC electric motors can be run in fixed-speed operation determined by the number of stator pole pairs in the motor and the frequency of the alternating current supply. AC motors can be made for "pole changing" operation, reconnecting the stator winding to vary the number of poles so that two, sometimes three, speeds are obtained.
