How to Protect Your AC Motor from Getting Damaged

November 04, 2016

AC motors are delicate when it comes to benefiting from their full potential. Although most have equivalent matches with the DC class of motors, AC motors are more susceptible to getting damaged. Here’s why you need to protect them from getting damaged, as well as ways of achieving that.


Use the right voltage

AC current differs in the number of phases, the oscillation frequency as well as the voltage. With each AC gear motor being designed to consume a given power limit, there is need to strictly comply with the operational standards given in the manufacturer’s instruction. This ensures that you do not short-circuit the motor with the excessive power overload. Always remember that using power sources of higher capacity or those from unstable production are likely to damage the motors. In case your estate or office block has higher above the standardized 240V power lines, you need to have a step down transformer to help you scale down the power to the specifications of the motor. 


Stick to the load capacity

Each AC gear motor has its optimum load capacity. This is determined by the specific horsepower of the revolving arm. To avoid damaging the motor, always ensure that no objects of higher load capacity than specified by the manufacturer is loaded on the arm. For a personalized review of the load capacity, check the horse power of the motor as well as the number of rotations per minute (rpm) when loaded at the optimum capacity. Any slower or faster rotation of the shaft might be an indicator that your motor is headed to being damaged.


Inspect the brushes regularly

In addition to maneuvering through the design specifications of the motor, there is need to regularly inspect the state and condition of the brushes. The carbon brushes in the AC gear motor ensures rapid transfer of the torque to the revolving shaft. Uneven or highly worn out edges might be an indicator that you’re motor is headed in the wrong direction. To restore it, ensure that you replace the brushes nearing the end of life.
