Brushless electric motor matched with a gearbox/controller, is an ideal kit for electrical cars. Controller software can be customized to the specific motor being used in the application, resulting in greater commutation efficiency. This motor has advantageous characteristics of DC motors (current and voltage are respectively proportional to torque and rotating speed) and AC motors (brushless structure). The Electric Motor. 0000012848 00000 n 60-80 Controllers that sense rotor position based on back-EMF have extra challenges in initiating motion because no back-EMF is produced when the rotor is stationary. [21] The advantage of linear motors is that they can produce linear motion without the need of a transmission system, such as ballscrews, leadscrew, rack-and-pinion, cam, gears or belts, that would be necessary for rotary motors. The device that moves the fields based on the position of the rotor is called a commutator.[4][5][6]. Servomotors are used for mechanical displacement, positioning or precision motion control. In various locations, more and more hydraulic systems are being replaced with motors. 0000009853 00000 n The most significant reason to switch to a brushless motor is a reduction in power required to operate them versus a typical AC motor. The maximum power that can be applied to a brushless motor is limited almost exclusively by heat;[citation needed] too much heat weakens the magnets and will damage the windings' insulation. Intermediate or large The brushless DC (BLDC) motor is becoming increasingly popular in sectors such as automotive (particularly electric vehicles (EV)), HVAC, white goods and industrial because it does away with the mechanical commutator used in traditional motors, replacing it with an electronic device that improves the reliability and durability of the unit. BLDC motors also offer high durability and low electric noise generation, thanks to the lack of brushes. There are various types of motor in common use. [12] Most electric bicycles use brushless motors that are sometimes built into the wheel hub itself, with the stator fixed solidly to the axle and the magnets attached to and rotating with the wheel.
