Have you paid attention to the selection of these magnetic particle dynamometers?
In the test of AC and DC motors and electric tools, dynamometers are often used as test equipment. The dynamometer mainly tests the torque, speed and output power of the motor. But not every magnetic particle dynamometer can meet all motor testing requirements. Three factors are mainly considered:
(1) Torque test range. The torque of the dynamometer usually cannot exceed the maximum torque value.
(2) Speed test range. The speed of the dynamometer usually cannot exceed the maximum speed that it can withstand. If it is used at high speed for a long time, it will greatly shorten the life of the dynamometer, especially the mechanical wear.
(3) The power usually marked on a magnetic particle dynamometer refers to the power that can be absorbed by the dynamometer, because the general dynamometer (hysteresis, magnetic powder, eddy current dynamometer is to absorb energy to absorb energy) Measure the output power of AC and DC motors or power tools. Strictly speaking, this index cannot be exceeded, otherwise the magnetic particle dynamometer will be easily burned because the heat cannot be dissipated.
The choice of magnetic particle dynamometer should not only meet the three main technical indicators of speed, torque, and power, but also whether it meets the specific requirements of the test. Generally, motors need to test no-load speed, no-load loss, and stall torque And other parameters also need to be focused on!
The magnetic particle dynamometer produced by Hailing Magnetic Powder Co., Ltd. has more advantages. When you buy products, you can refer to the manufacturer's recommendations in order to select equipment that is beneficial to production.
