Electric Motor Torque Testing

Magtrol s dynamometers electronics and software are used for testing all types of electric and pneumatic motors gas engines and gearheads as well as servo drives and inverters.

Electric motor torque testing.

Electric motors have had a reputation for being a mix of science and magic. Comprehensive torque characteristics analysis for small electric motors and actuators. So when a motor fails to operate it may not be obvious what the problem is. N revolution per minute rpm alternatively.

Hysteresis eddy current and powder. Motor testing can also identify when a high efficiency motor is not meeting its potential because of incorrect rewinding or core loss. I am a firm believer in using manufacture torque requirements i have been in the mining industry as electrical troubleshooter for 30 years and over 90 of failures caused by tightening methods i also will move the wire around and torque again this has proven to help in maintaining torque specs when wires are moved into position to close cabinet. If the torque is too low the nut could vibrate or become loose.

An electric motor e motor test stand also referred to as bench is a test stand for reproducible testing of electric motors in addition to the mechanical design an electric motor test stand consists of accompanying measurement devices sensors and application software the bus systems used to control and monitor the test objects are also included in the test stand. Torque in imperial units can be calculated as. Torque testing involves measuring the amount of torque being applied to an object. Begin to check the bearings of the motor.

T ftlb torque lb f ft. Testing electric motors doesn t have to be a mystery. Electrical motor power velocity and torque equations. In an electric motor the effects of each of the stator brushes on each rotation can be seen.

Bearings are located at both ends of the motor which are sometimes called bell housings or end bells. The bearings allow the shaft or rotor assembly to turn freely and smoothly in the frame. Sugawara laboratories provides a family of motor torque meter. 1 ft lb f 1 356 nm.

T inlb torque in lb f. T inlb p hp 63025 n 1. Two of the more common applications for torque testing are in fastening and in products with rotating parts such as motors engines or transmissions. Electric motor testing pinpoints problems with power supply that may be reducing a motor s life span and increasing energy costs.

Torque and rotor bar signatures. Two of the more common applications for torque testing are in fastening and in products with rotating parts such as motors engines or transmissions. T ftlb p hp 5252 n 1b. Motor torque testing systems.

This type of motor test. Bolt torque testing is also known as fastener testing. Many electric motor failures are caused by bearing failures. Motor test equipment magtrol offers three types of dynamometers each with a different braking system to absorb load.
