Direct drive motor or alternator

A direct drive motor or alternator is a motor that is directly coupled to its load or an alternator to its driving engine or turbine without using a gear. As a matter of fact, the gears create problems of maintenance,  reliability, accuracy and loss of efficiency that  penalize technically and economically the servomechanisms. That is the reason why the machine builders have initiated since several years to eliminate the gears by using motors rotating at low speed and consequently with  high torque capability for achieving  a direct drive of the automated axis.The motor  may operate with various energy sources. In the case of ALXION,  we are focused on direct drive electrical motors and more particularly permanent magnet AC 3 phase direct drive motors and alternators with our ranges of ST complete motors,  STK frameless motors and STK frameless alternators.
