Motor Tester

A reliable source for Dynamometers and leading Dynamometers Companies & Manufacturers.

Motor testers are used to determine if repairs are necessary and to perform maintenance and troubleshooting in order to minimize downtime and avoid repair costs. A routine test can help maintain the motor’s efficiency so that the lifespan of the equipment will be extended. Read More…

Motor Tester Motor testers measure the performance of motors to ensure that they are efficient and safe. The equipment is automatic, performing a sequence of steps to determine whether the demonstrated capabilities of the motor are acceptable. The majority of motor testers are used with electric motors.

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.

Motor Tester Motor Tester - SAKOR Technologies, Inc.

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.
