Electric Motor Torque Testing

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 torque testing.

T ftlb p hp 5252 n 1b. Bolt torque testing is also known as fastener testing. An accurate grasp of load characteristics cogging torque characteristics and torque ripple characteristics is critical for electric motor performance evaluations. N revolution per minute rpm alternatively.

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. 1 ft lb f 1 356 nm. The bearings allow the shaft or rotor assembly to turn freely and smoothly in the frame. T ftlb torque lb f ft.

Torque testing involves measuring the amount of torque being applied to an object. Torque and rotor bar signatures. Bearings are located at both ends of the motor which are sometimes called bell housings or end bells. This type of motor test.

So when a motor fails to operate it may not be obvious what the problem is. Torque in imperial units can be calculated as. T inlb torque in lb f. Comprehensive torque characteristics analysis for small electric motors and actuators.

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. Many electric motor failures are caused by bearing failures. Testing electric motors doesn t have to be a mystery. Two of the more common applications for torque testing are in fastening and in products with rotating parts such as motors engines or transmissions.

P hp horsepower delivered by the electric motor hp. If the torque is too low the nut could vibrate or become loose. Begin to check the bearings of the motor. Motor torque testing systems.

Electric motor testing pinpoints problems with power supply that may be reducing a motor s life span and increasing energy costs. In an electric motor the effects of each of the stator brushes on each rotation can be seen. Motor test equipment magtrol offers three types of dynamometers each with a different braking system to absorb load. Knowledge of the basics together with powerful new test equipment vastly simplifies the job.

Motor testing can also identify when a high efficiency motor is not meeting its potential because of incorrect rewinding or core loss. Electrical motor power velocity and torque equations. Electric motors have had a reputation for being a mix of science and magic. Hysteresis eddy current and powder.
