• Introduction of the Variable Frequency Motor    

Variable frequency motor can realize different speed and torque under the drive of frequency converter to meet the demand of load change. The general frequency conversion motor is derived from the traditional squirrel cage motor; The traditional self cooling fan is usually replaced by an independent fan, and the corona resistance of the motor winding insulation is improved.

Variable speed drive motor refers to the motor that operates continuously at 100% rated load and 10%~100% rated speed under standard environmental conditions, and the temperature rise will not exceed the rated allowable value of the motor.

Variable frequency motor in Class B temperature rise design, Class F insulation manufacturing. The use of polymer insulation materials, vacuum pressure impregnation manufacturing process and special insulation structure has greatly improved the insulation withstand voltage and mechanical strength of the electrical winding, which is competent for high-speed motor operation and resistance to high-frequency current impact of frequency converter and damage to insulation caused by voltage.

The balance quality is high, the vibration level is R (vibration reduction level), the machining accuracy of mechanical parts is high, and special high-precision bearings are used, which can operate at high speed.

The forced ventilation and heat dissipation system adopts imported axial flow fans, which are ultra quiet, long-life and strong wind. It can ensure that the motor can get effective heat dissipation at any speed, and can realize high-speed or low-speed long-term operation.

• Variable Frequency Three-phase Asynchronous Motor Tectonic principle

When the slip rate of AC induction motor changes little, the speed is proportional to the frequency. It can be seen that changing the power frequency can change the speed of asynchronous motor. Variable speed motor is always hoped that the main magnetic flux will remain unchanged during variable frequency speed regulation. If the main magnetic flux is greater than the magnetic flux during normal operation, the magnetic circuit will be over saturated, which will increase the excitation current and reduce the power factor; If the main flux is less than the flux during normal operation, the motor torque will decrease.

• Application of variable frequency drive motor

Variable frequency motors are superior to ordinary motors for occasions requiring frequent start, frequent speed regulation, and frequent braking.

With the rapid development of power electronics technology and new semiconductor devices, the AC speed regulation technology has been constantly imporved. The gradually improved frequency converter has been widely used in AC induction motor with its good output waveform and excellent performance price ratio: Large motors, medium and small roller table motors for steel rolling, traction motors for railway and urban rail transit, elevator motors, lifting motors for container lifting equipment, motors for water pumps and fans, compressors, household appliances.
