Efficient Motors

The new Energy Efficient Motor is desgined for a range of Industrial or Commercial applications.

Regenerative braking is possible, giving increased range and longer brake life in vehicles used in stop-start traffic or on hilly roads.

Can also operate as a generator. Weight about 11Kg. Up to 9KW (12 horsepower) at 60 volts, at only 3000 rpm. Applications requiring less power can use lower voltages, giving even lower speeds which in most applications will allow the transmission to be cheaper and more efficient.

The 135 Disc motor has a speed of about 50 rpm for each volt. The maximum continuous current varies from about 80 amps at 12 volts to 160 amps at 60 volts; the limiting factor is the flow of cooling air through the motor and the continuous current at low voltages may be increased if ventilation is good.

Maximum efficiency is produced when running at about half the maximum continuous current. Normally the motors should be controlled with an electronic speed controller of the type using MOSFETs with a switching frequency of 15 KHz or higher. ( video clip )
