Overview

Main Characteristics

1. Fully replaces DC motor speed regulation, frequency converter + frequency conversion motor speed regulation, and asynchronous motor + reducer speed regulation.
2. Incorporates all advantages of traditional DC motors while eliminating carbon brushes and slip ring structures.
3. Enables low-speed high-power operation, allowing direct drive of large loads without a reducer.
4. Small in size, light in weight, and high in output.
5. Excellent torque characteristics, with good medium and low-speed torque performance, large starting torque, and small starting current.
6. Stepless speed regulation with a wide speed range and strong overload capacity.
7. Soft start/stop and good braking characteristics, eliminating the need for original mechanical or electromagnetic braking devices.
8. High efficiency, with no excitation loss or carbon brush loss in the motor itself, eliminating multi-stage deceleration losses. The comprehensive power saving rate can reach 20%–60%, and the purchase cost can be recovered within one year through power saving alone.
9. High reliability, good stability, strong adaptability, and simple maintenance.
10. Resistant to (bumping and vibration), low noise, small vibration, smooth operation, and long service life.
11. No radio interference, no spark generation, particularly suitable for explosive environments, with explosion-proof types available.
12. Optional trapezoidal wave magnetic field motors or sine wave magnetic field motors as needed.

Motor Selection

• Maximum Torque: Calculated by summing load torque, moment of inertia, and friction force, with additional factors such as air gap resistance influencing it.
• Square Mean Torque: Approximately the continuous output torque required for practical applications, determined by multiple factors: maximum torque, load torque, moment of inertia, acceleration, deceleration, and operation time.
• Speed: The speed required by the application, determined based on the motor's speed trapezoidal curve. A 10% margin is typically reserved during calculation.
