Characteristic of Brushless Electric Motor

1. It can replace DC motor speed regulation, frequency converter+variable frequency motor speed regulation, and asynchronous motor+reducer speed regulation.

2. It has the advantages of traditional DC motors, while also eliminating carbon brush and slip ring structures.

3. It can operate at low speed and high power, eliminating the need for the gearbox to directly drive large loads.

4. Small size, light weight, and high output.

5. Excellent torque characteristics, good torque performance at medium and low speeds, high starting torque, and low starting current.

6. Stepless speed regulation, with a wide speed range and strong overload capacity.

7. Soft start, soft stop, and good braking characteristics can eliminate the need for existing mechanical or electromagnetic braking devices.

8. High efficiency, the motor itself does not have excitation losses and carbon brush losses, eliminating multi-level deceleration losses, and the comprehensive power saving rate can reach 20%~60%.

9. High reliability, good stability, strong adaptability, and simple maintenance and repair.

10. Resistant to bumps and vibrations, low noise, low vibration, smooth operation, and long service life.

11. It does not generate sparks and is particularly suitable for explosive locations, with explosion-proof type.

12. Select trapezoidal wave magnetic field motor and sine wave magnetic field motor as needed.

Model Selection

The main parameters to refer to when selecting brushless DC motors are as follows:

1.Maximum torque: it can be obtained by adding the load torque, Moment of inertia and friction. In addition, there are some additional factors that affect the maximum torque, such as the resistance of air gap air.

2.Square modulus torque: it can be approximately considered as the continuous output torque required for practical application, which is determined by many factors: maximum torque, load torque, Moment of inertia, acceleration, deceleration, operation time, etc.

3.Speed: This is the speed that has application requirements, and the speed demand of the motor can be determined based on the trapezoidal curve of the motor speed. Usually, a 10% margin should be left in the calculation.
