Brushless Water-cooled DC Motors

1.Brushless structure. 2.High startup torque. Low startup current 2.Permanent magnet. High efficiency 3.Well heat emission

1.Brushless structure, excellent load characteristics, good low-speed performance, high staring torque, low starting current, suitable for frequent startup of Electric Vehicles, saving energy

2.Motors operate efficiently in the whole speed range, much improved compared with brush DC motors and AC variable-frequency motors (Only having high efficiency at rated point ), extending the driving range and battery life.

3.No spark, do not need brushes, compact structure, good overload ability, long life

4.Motors adopt embedded rare-earth magnet steel, suitable for the need of bumping, repeating startup, high speed, high torque startup, reversible startup.

5.The rotors of the motor have strong magnetic field, good generating effect when sliding and braking. Do not need battery power for excitation, good power feedback and braking effect.

6.Motors adopt wind cooling or water cooling, low temperature, adopt imported oil-contained high speed bearings, maintenance free, high reliability, long life.

7.The motors have horizontal type, hanging type, could have cover with flange front edge, Biaxial stretching, spline shaft. The voltage and power can be customized according to the vehicle’s requirements. The motor can be made as motor-generator ones.
