Introduction of the Variable Frequency AC Motor
Variable frequency motor is a kind of AC motor. Variable frequency motors can realize different speeds and torque under the frequency converter's drive to meet the load change demand. 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.
Core Features of VFD AC Electrical 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 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.
