一个 Magnetic Powder 测功机 is a testing device that uses magnetic powder to generate braking torque. It is ideal for testing motors, transmissions, and machinery requiring high torque at low or medium speeds. The device provides full torque at zero speed and offers precise control over braking force.

Operating Principle

1. Magnetic Powder Technology: Fine magnetic powder is placed between the rotor and stator.
2. Electromagnetic Field: Electrical current through the coil generates a magnetic field.
3. Torque Generation: Magnetic powder changes its properties under the magnetic field, creating smooth braking torque.
4. Frictionless Operation: Torque is transmitted without mechanical contact, reducing wear.
5. Precise Control: Torque is infinitely adjustable via the excitation current.
