Powering two- to three-wheelers in Asia

FRIWO has developed a motor control unit and software specifically for two- and three-wheel vehicles in Asia, writes Nick Flaherty. The MC1.5-55A-48V unit has a continuous power output of 1.5 kW for light EVs using permanent magnet synchronous motors (PMSM), making it ideal for electric scooters, motorcycles and other vehicles, particularly in India, Vietnam and Indonesia, and generally in Southeast Asia.

Motor development and manufacturing

Peter Donaldson details the many processes involved in creating new motor systems. As with any sophisticated industrial process, the development of motor systems for e-mobility is a complex and multi-stage endeavour, subject to rapid change under pressure, both to innovate and ramp up to high production volumes.

Coveme electric motor slot and battery spacer insulation for high-voltage applications

With motor voltages in many e-mobility applications effectively doubling from the 400V region to 800V or more, one of the issues that arises is preventing breakdown of the insulation within the motor slots, the key stressor being partial discharges.

bdtronic’s new machine targets the impregnation of windings

bdtronic’s B8650 impregnation machine enhances electrical component manufacturing, targeting the impregnation of windings in rotors, stators and coils used in electric motors.

Deep Insight

Coil windings

Peter Donaldson takes electric machines apart to examine the inner workings of coil windings. At first glance, electric machines are simple. They have one moving part, the rotor, which either rotates in response to an input of electrical energy or puts out an electric current in response to an input of mechanical energy that rotates it.
