Solution:Burnt out motor(s)

 

Causes:

Motors can be damaged by a number of different problems. Some of the most common are:
  1. Incorrect voltage
  2. Motor thermal protection / overcurrent protection settings
  3. Excessive jogging
  4. Over heating 
  5. Contactor failure (contacts welded closed)

Solutions:

  1. Verify the incoming voltage is compatable with the motor. If the motor is rated for a different voltage than what is present a transformer can be installed or the correct motor can be installed.
  2. Verify the current draw of the motor and set protective devices accordingly 
  3. Excessive jogging can cause a motor to overheat and ultimatly shorten the life span of the motor. One solution for this is a VFD or motor drives. A properly configured drive will extend the life of a motor and prevent motor burn outs. Click here to see our drives.
