FAQ
What is DC motor control method ?
In this control mode, the phase current waveform of the motor is close to a square wave, so it is called square wave control.
The advantage of square wave control is that the control algorithm is simple, the hardware cost is low, and the general performance of the controller can obtain higher motor speed. The disadvantage of square wave control is that the torque fluctuation is large, there is a certain current noise, and the efficiency cannot reach the maximum , Square wave control is suitable for occasions where the motor rotation performance is not required.
The sine wave control method adopts SVPWM wave, the output is a three-phase sine wave voltage, and the corresponding current is also a sine wave current. This method does not have the concept of square wave control commutation, and does not consider the existence of infinite commutation in the electric cycle. Obviously, compared with square wave control, sine wave control has smaller torque ripple and smaller current harmonics, and it feels more "fine" in control. However, the performance requirements of the controller are slightly higher than those of square wave control. The efficiency cannot be maximized.
The sine wave control realizes the voltage vector control, and indirectly realizes the current magnitude control, but cannot control the current direction. The FOC control mode can be regarded as an upgraded version of the sine wave control, which realizes the current vector control and the stator magnetic field vector control.
Because the direction of the stator magnetic field is controlled, the stator magnetic field and the rotor magnetic field can be kept at 90 degrees at any time, so as to achieve the maximum torque output under a certain current. The advantages of the FOC control method are: small torque fluctuations, high efficiency, and low noise , The dynamic response is fast; the disadvantages are: high hardware cost, high requirements for controller performance, high requirements for motor parameter matching, because FOC has obvious advantages, it gradually replaces traditional control methods in many applications, in the sports control industry Has been widely used.
