What can cause high amperage on a motor?
What can cause high amperage on a motor?
Last answer:
High amperage can result in a motor when the amount of load increases. when load increases , it reduces the rotor speed which increases the slip at constant synchronous speed ... , as a result more current shall have been drawn to maintain the additional load.
