Electromagnetic DC servo motors, MA Series
 
These asynchronous motors have been specially engineered to achieve dimensions of dc motors of similar power and to be suitable for high performance, flux vector type controllers in variable speed applications. Maximum speed is up to 8000 RPM. The efficient stator cooling system uses an auxiliary electro fan to combine the benefits of reduced dimensions and high, continuous, low-speed torque capability.
