Clarification:
Motor speed is 240 RPM. The timer speed is 0.0037 RPM with speed reduction from the motor to the timer cam achieved through a gear train. Sorry for the confusion. The test monitors timer operation only (motor start, correct motor rotation, and contact switching/timing)...
I'm trying to determine if testing small synchronous PM motors (used as timing devices in appliance controls) at high frequencies (up to 600 Hz) will damage the motor during production audit testing. These motors are rated at 115 VAC 60 Hz with a speed of 0.0037 RPM (1 RPM/271 minutes). In...
