Motor Tester List
Motor testers have a variety of operating procedures to perform electric motor impulse testing, motor rotation testing, wound rotor motor testing, electric motor insulation resistance testing and more. This equipment can operate offline without a power supply or online with applied power and a running motor.
Depending on the application, motor testers may be portable, standalone or installed in the equipment being tested. Because of the widespread usage of both gas and electric motors, motor testers are very important to many industries. Production and manufacturing companies rely on functioning and efficient motors for every process that requires power or motion. These machines may also be used for vehicles.
Motor testers are available in a range of styles, sizes, methods and abilities. Top quality testers perform more complicated analyses, storing and exporting data and graphing it on digital displays. Generally, motor testers work by using voltage probes and current probes attached to input wires of the motor to connect internal voltmeters, ammeters and ohmmeters to the system (only for electrical motors).
Some use a non-contact speed sensor to measure the motor shaft speed and determine the number of rotations per minute. Other options and parameters include a load point test where the motor is tested while under a full load, no load or a locked rotor.
Direction, torque, current, voltage, power, efficiency and cut-out speed may be determined by motor tester equipment because of the range of available options that meet the variety of needs. Much like a torque tester, motor testers may take torque measurements by using a trunnion mounting of the loading device where the brake is mounted so that its enclosure is able to rotate freely around the shaft.
An electronic scale takes the measurements. Transducers coupled with the shaft between the motor and the brake is very fast and accurate with less than 0.1% inaccuracy. For motor power, testers are able to handle speeds from less than one horsepower to several hundred.
