Electric motor torque testing.

This type of motor test. 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. Sugawara laboratories provides a family of motor torque meter. T inlb p hp 63025 n 1.

Knowledge of the basics together with powerful new test equipment vastly simplifies the job. P hp horsepower delivered by the electric motor hp. Motor test equipment magtrol offers three types of dynamometers each with a different braking system to absorb load. 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.

Comprehensive torque characteristics analysis for small electric motors and actuators. Motor torque testing systems. T ftlb torque lb f ft. T inlb torque in lb f.

Begin to check the bearings of the motor. Motor testing can also identify when a high efficiency motor is not meeting its potential because of incorrect rewinding or core loss. Two of the more common applications for torque testing are in fastening and in products with rotating parts such as motors engines or transmissions. The bearings allow the shaft or rotor assembly to turn freely and smoothly in the frame.

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. Bolt torque testing is also known as fastener testing. Testing electric motors doesn t have to be a mystery. T ftlb p hp 5252 n 1b.

Two of the more common applications for torque testing are in fastening and in products with rotating parts such as motors engines or transmissions. N revolution per minute rpm alternatively. Torque in imperial units can be calculated as. Electric motors have had a reputation for being a mix of science and magic.

Hysteresis eddy current and powder. Electric motor testing pinpoints problems with power supply that may be reducing a motor s life span and increasing energy costs. Many electric motor failures are caused by bearing failures. An accurate grasp of load characteristics cogging torque characteristics and torque ripple characteristics is critical for electric motor performance evaluations.

In an electric motor the effects of each of the stator brushes on each rotation can be seen. Electrical motor power velocity and torque equations. Bearings are located at both ends of the motor which are sometimes called bell housings or end bells. So when a motor fails to operate it may not be obvious what the problem is.
