Dale et al,
The CIM stall current is 133 amps but more importantly to our use the CIM is not ventilated. Prolonged high currents cause internal heating that damages the windings insulation and eventually leads to electrical failure of one or more windings. The bearings on a CIM are not designed for significant side loading and for many teams, this is an issue. If you are not using the CIM in a transmission for which it was designed, you need tor provide additional bearing support to the shaft end or friction will raise your load currents and eventual bearing damage will result. Remember that the CIM was designed for a special use in which the loads were intermittent and the speed relatively constant with no side loads on the bearing. Although CIMs have failed in our use, most were due to rough handling as described above. Long term heavy use, i.e. demo, can cause excessive heat. Keep an eye on motor heating and give the motors a chance to cool off before using again.
