The high voltage dc motor suppliers tells you the merits of a DC motor.
DC motor is another name for DC motor. According to the working principle of DC motor, it has the following advantages compared with AC induction motor:
1. The rotor uses a magnet and no magnetic current is required to obtain greater mechanical power.
2. The rotor has no copper damage and iron damage, and the temperature rise is smaller.
3. The opening and blocking moment is large, which is conducive to the characteristics of the moment when the valve is opened and closed.
4. The output torque of the motor is proportional to the operating voltage and current. The torque detection circuit is simple and reliable.
5. By adjusting the average of the power supply voltage by pulse width modulation, the motor can be smoothly adjusted. Speed adjustment, drive power circuit simple and reliable, low cost.
6. The power supply voltage start-up motor can be reduced by pulse width modulation to effectively reduce the start-up current.
7. Electrical power supply is a DC voltage modulated by pulse width. Compared with the sine wave AC power supply of AC frequency converter motor, the speed regulation and drive circuit produces less electromagnetic radiation and less harmonic pollution to the power grid.
8. The closed-loop speed control circuit can be used to change the motor speed when the load moment changes.
