The BLDC motor, a typical mechatronics product, includes the motor body and drive. Advantages of BLDC motor: 1. With excellent linear mechanical characteristics of DC motor, wide speed range, stepless speed regulation, wide speed range; 2. Excellent torque characteristics, good medium and low speed ...
First, BLDC motor can replace DC motor speed control, inverter + frequency conversion motor speed control, asynchronous motor + reducer speed control; Second, BLDC motor has the advantages of traditional DC motors, while eliminating the structure of carbon brushes and slip rings; Third, BLDC motor c...
1. Direct Torque Control Direct torque control has the advantages of simple structure, fast torque response, good robustness to parameters, etc., but it is a control method based on the Bang-Bang control of a single vector, torque and flux linkage hysteresis. Inevitably, the low-speed switching freq...
SVPWM Control Method SVPWM (Space Vector Pulse Width Modulatlon, space vector pulse width modulation) control method is a relatively new control method developed in recent years. It is a pulse width generated by a characteristic switching mode composed of six power switching elements of a three-phas...
