What can be done to overcome the heating problem?
The provisions for overcoming the heating problem in a vacuum are as follows: 1) Permit the motor to withstand higher temperatures Empire Magnetics laboratory, standard and commercial grade vacuum rated motors are made to withstand internal temperatures of 180 C, 155 C, and 130 C, respectively. 2) Select the appropriate drive electronics a low voltage drive and a series connection will reduce motor heating. The reduced standby current option offered by many drives may also be employed to reduce motor heating. 3) Limit the duty cycle when possible, reduce or turn off the current to the motor when it is not being used. this is a simple and effective way to reduce motor heating. 4) Improve the heat transfer mechanisms conduction through the mounting surface can be improved by creating a simple heatsink consisting of metal tubing with cool fluid running through it.
