3 Things That Will Make an Electric Motor to Fail (Plus What You Can Do)
Electric vibrating motors have a range of applications in the modern world. Some of the common uses include powering water pumps in homes and electric vibrators used in the construction of concrete slabs. Regardless of their use, electric vibrating motors often run into problems during start-up or in the course of using them. This can be attributed to the operating conditions of the motors or installation problems that hinder the efficient operation of the motor. Here are some of the problems you might encounter when using electric vibrating motors:
Low Insulation Resistance
Low insulation resistance is one of the common problems you will encounter when using electric vibrating motors. Basically, low insulation resistance refers to the inability of low voltage cables to stand to shorts, which could damage the motor on start-up or during usage. Immediately after the motor is installed, the insulation resistance of the cables is usually over one thousand mega ohms. However, the value of the resistance diminishes over time as the insulation decays. You need to restore the insulation immediately so that the damage doesn't affect other parts of the motor.
When buying or hiring the motor, remember to ask for an automatic device that measures its insulation resistance. Monitor the resistance from time to time and restore it every time it falls below five hundred mega ohms. Additionally, install some safeguard rotating equipment to prevent anticipated failure.
Dirt and Grime
Dirt is another common cause of failures in electric vibrating motors. First, dirt can build up and block the fan, preventing it from cooling the motor efficiently. This causes the motor to overheat. Additionally, dirt also affects the insulation value of the windings in the motor hence lowering the resistance. Thankfully, shielding devices are available in motor supply stores near you. Buy them for your motor to make it dust proof.
Vibration and Corrosion
A slight vibration of the motor is expected in high power applications that draw lots of power from the motor. However, extreme vibrations are an indication of a mechanical problem with the motor. Such vibrations result from misalignment of the motor, and it must be checked to restore normal functioning. Moreover, corrosion of the motor parts makes them weak and unable to stand to the rigours of the work at hand. Corrosion can result from exposure of the motor to high amounts of moisture or corrosive gaseous chemicals. For this reason, you must keep the motor dry at all times.
