How important are the precautions for using magnetic particle dynamometers, are you aware?

Magnetic powder dynamometer is composed of stator, solid rotor, exciting coil, magnetic powder medium, bracket, bottom plate, etc. When the internal coil of the magnetic powder dynamometer passes a current, a magnetic field is generated, so that the internal magnetic powder is arranged into a magnetic chain according to the magnetic field lines. The pulling force becomes resistance to prevent the rotor from rotating, and this force is the load torque. Changing the exciting current can change the load torque.
The magnetic particle dynamometer is suitable for testing motors in the low to medium speed or medium to high torque range, and can provide maximum torque at zero speed. Such as starter motor constant torque on-load starter, asynchronous motor, DC geared motor, single-phase asynchronous motor, electric vehicle motor and constant tension control used in papermaking, textile and other industries. Both the magnetic particle dynamometer and the eddy current dynamometer use water cooling, and the maximum test power can reach 14KW.


Let's take a look at the matters needing attention when magnetic particle dynamometer:
1. The magnetic powder tester must be warmed up for half an hour before the motor runs.
2. Pay attention to the matching of thread colors when wiring.
3. Check whether the screws and positioning pins are tight before testing.
4. When the test time is too long, be sure to start the coolant.
Magnetic particle dynamometer is an important equipment in the production of enterprises. The magnetic particle dynamometer produced by our company is strictly inspected and shipped from the factory in accordance with process standards.
