Electric Motor Torque Testing

Hysteresis eddy current and powder.

Electric motor torque testing.

Many electric motor failures are caused by bearing failures. Torque in imperial units can be calculated as. Motor torque testing systems. So when a motor fails to operate it may not be obvious what the problem is.

Torque and rotor bar signatures. 1 ft lb f 1 356 nm. T ftlb torque lb f ft. Electrical motor power velocity and torque equations.

N revolution per minute rpm alternatively. Bearings are located at both ends of the motor which are sometimes called bell housings or end bells. Comprehensive torque characteristics analysis for small electric motors and actuators. If the torque is too low the nut could vibrate or become loose.

T inlb torque in lb f. The bearings allow the shaft or rotor assembly to turn freely and smoothly in the frame. 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. T ftlb p hp 5252 n 1b.

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. Begin to check the bearings of the motor. In an electric motor the effects of each of the stator brushes on each rotation can be seen. Electric motor testing pinpoints problems with power supply that may be reducing a motor s life span and increasing energy costs.

Motor test equipment magtrol offers three types of dynamometers each with a different braking system to absorb load. This type of motor test. P hp horsepower delivered by the electric motor hp. An accurate grasp of load characteristics cogging torque characteristics and torque ripple characteristics is critical for electric motor performance evaluations.

Bolt torque testing is also known as fastener testing. Motor testing can also identify when a high efficiency motor is not meeting its potential because of incorrect rewinding or core loss. Sugawara laboratories provides a family of motor torque meter. Testing electric motors doesn t have to be a mystery.

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. 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. Knowledge of the basics together with powerful new test equipment vastly simplifies the job.
