Product performance:

The basic principle of switched reluctance speed regulation system is the principle of reluctance minimization, which has a series of good characteristics, mainly:

1, good starting characteristics

The controller side absorbs 30% of the rated current, and the motor side can output 2 to 3 times the starting torque. Other speed control systems require 7 to 8 times the starting current to obtain 2 times the starting torque. This performance determines that the switched reluctance speed regulation system can carry out frequent positive and negative rotation operation (that is, positive electrical operation, positive electrical braking operation; Reverse electrical operation, reverse electrical braking operation) or a difficult electrical operation state that frequently starts and stops running.

2, good low speed characteristics

The mechanical characteristics of the switched reluctance speed control system are as follows:

(Assuming that the rated speed is 1500r/min), that is, 100r/min-500r/min, 500r/ min-1000R /min-1500r/min, can output rated torque. At 500r/min, only about 1/3 of the rated current is needed to output the rated torque; At 1000r/min, only about 2/3 of the rated current is needed to output the rated torque. Therefore, in the state of long-term low-speed operation, high efficiency and energy saving, the motor does not heat.

3, wide speed range, speed ratio greater than 20:1.

Switched reluctance speed control system has a wide range of speed control, smooth and stepless speed control. Because of the special structure of the switched reluctance speed regulating motor, there is no winding and no magnetic steel on the rotor, which is suitable for high-speed operation. Therefore, it is suitable for the design and manufacture of high-speed motors.

4, good load characteristics

Switched reluctance speed control system adopts the strategy of current closed loop and speed closed loop, which has high speed stability accuracy. The speed stabilization accuracy is controlled at ±0.3%. As the load increases or decreases, the speed remains the same.

5, the motor is strong and maintenance-free operation

The rotor of the reluctance motor is only made of silicon steel sheet laminated, without any winding, no squirrel cage bar, under the effective protection of the controller, the motor can achieve lifelong maintenance free operation.

6, high efficiency and energy saving

♦ The performance of the switched reluctance speed regulation system determines its high system efficiency. It is mainly manifested in:

♦ High starting efficiency, low current starting, high starting torque.

♦ Low speed efficiency, with a small current to obtain a larger constant torque. Full speed range high efficiency
