Features
1. The motor features an asynchronous starting and highly efficient synchronous running.
2. It replaces traditional variable frequency motors, and combinations of a variable frequency motor and reduction box, as well as the combination of traditional micro or small three phase asynchronous motors and reduction boxes.
3. The low speed motor has all the advantages of a brush synchronous motor, however, it removes the need for a slip ring and armature structure.
4. Running on large amounts of power and at a low speed, direct drive operation of a reduction box is avoided.
5. An excellent torque characteristic and strong overload resistance add to the high power density.
6. The low vibration noise, excellent stability, smooth operation and little to no need for maintenance add to the overall long service life.
7. The low starting impulse current can use a frequency converter to adjust the speed.
8. The motor will always maintain normal operations, even under a heavy load. The efficiency is higher by 10 to 35% than induction motors of the same power, adding to the wide applicability range.
