David_Lee Posted August 20, 2003 Report Share Posted August 20, 2003 Hi, My motor is very hot. Any suggestion to reduce the temperature is appreciated.Motor information: 1. Stepper motor 2. 24V power supply 3. Phase control 4. Drive IC MC1413 of on semiconductor Thanks and best regards David (Email: lizh@calcomp.com.sg) Link to comment Share on other sites More sharing options...
TUGCE Posted August 20, 2003 Report Share Posted August 20, 2003 Hi,It can be a lot of reason to hot motor, you should check the current which the motor under the load. This current must be equal the current which written on the nameplate. Reason of over temperature;Overload the deviation on the shaft line Link to comment Share on other sites More sharing options...

David_Lee Posted August 21, 2003 Author Report Share Posted August 21, 2003 Hi, Just as you said, the current is high. But it is not becasue of the overload since even I free the motor, the current is still high. Any further suggestion? Thanks David Link to comment Share on other sites More sharing options...
BigMax Posted September 9, 2003 Report Share Posted September 9, 2003 Hi all, Stepper motors are usually fairly inefficient and as a result can run surprisingly warm. Is the stepper motor actually rated at 24VDC? If so, without series resistors? Is it required to run at low speed for extended periods (low speeds produce more loss)? Perhaps the temperature rise is 'normal'. Cheers! BigMax:P Link to comment Share on other sites More sharing options...
grobert Posted October 11, 2003 Report Share Posted October 11, 2003 If your supply voltage matches the nameplate voltage and your current with no load is greater than motor nameplate, you have a problem. I would run motor across the line and see if amps are still high. You may need to replace the motor and or drive. As far as the heat , typical motor rated at 40deg. C. which can be quite warm to the touch. The ambient temperature and air space around motor can also effect a motors self cooling abillity. Have you used a temp probe to read actual temp? I must add that this is typical motor troubleshooting. I have no real experience with "stepper" motors. Link to comment Share on other sites More sharing options...

Guest Posted February 16, 2005 Report Share Posted February 16, 2005 Hi , I dont have much experience on motor but i can have suggestions: 1. check the frequency of your motor..motor of 50 hz if run on 60 hz system will produce more torque which cause increase in your motor speed which will in turn produce more current than its normal rating.More current means more heat....... 2.check the quality of your controller........
