Permanent magnetic rotor tester

This series of products is suitable for testing the electrical performance of various DC brushless motor outer rotor and inner rotor, such as the rotor of washing machine motor, mid-drive motors, air conditioner motor and other home appliance motor. The rotor tester consists of test tooling, industrial computer, test host, system control software and various function modules, etc. It realizes the test of DC brushless rotor motor's Back-EMF and Hall characteristic test, and the equipment will complete the test items of set program as preset sequence after starting, and give the qualified and unqualified indication and sound and light alarm after the test is completed. Light curtain is installed at the entrance of the equipment operation area to protect the operator's personal safety.

MES: support connecting with the production management system.

Technology

Test Items： Back EMF, Hall characteristics (high and low voltage, frequency, duty cycle, Hall waveform), the Phase difference (back EMF, Hall, Back EMF, and Hall)

Tester can test the permanent magnet motor with the inner rotor and outer rotor.

Test objects: home appliance motors, power tool motors, pump motors, automotive motors, and other types of permanent magnet rotors.


Ultra-high precision tooling design, to ensure uniform stator and rotor air gap, stable and accurate testing.

Problems can be detected in advance before the motor is assembled and save cost. BEMF test can detect whether the rotor is unevenly magnetized and the poor magnetization issue effectively.

FAQ
  • What motor has a permanent magnet rotor?

    A permanent magnet synchronous motor (PMSM) is an electric motor that uses permanent magnets to generate the magnetic field necessary for its operation. PMSMs are commonly used in a variety of applications, including electric vehicles, industrial machinery, and renewable energy systems.

  • What kind of magnets are used in rotors?

    The magnetic field for a synchronous machine may be provided by using permanent magnets made of neodymium-boron-iron, samarium-cobalt, or ferrite on the rotor. In some motors, these magnets are mounted with adhesive on the surface of the rotor core such that the magnetic field is radially directed across the air gap.

  • Are permanent magnet motors AC or DC?

    A permanent magnet (PM) motor is an AC motor that uses magnets embedded into or attached to the surface of the motor's rotor.

  • Does Tesla use permanent magnet motors?

    Further, rare earth elements are not used in every type of electric car motor – Tesla uses them in DC permanent magnet motors but not in its AC induction motors. Originally, Tesla used AC induction motors in its vehicles, which did not need rare earth elements.

  • What is the difference between a permanent magnet motor and a servo motor?

    Permanent Magnet: Magnets on or in the rotor work with the motor's magnetic fields; Servomotor: Uses feedback signals to control closed loop systems – work is variable.
