Introduction of the Variable Frequency AC Motor
Product Description of Milestone 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 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.
Advantage of the variable frequency motor?
Variable frequency motor has many advantages, so it has been widely used. The advantages of variable speed motor are as follows:
|
(1) Easy speed regulation and energy saving. |
| (2) AC induction motor has a simple structure, small volume, small inertia, low cost, easy maintenance, and durability. |
| (3) The capacity can be expanded to achieve high speed and high voltage operation. |
|
(4) Soft start and fast braking can be realized. |
| (5) Non-sparking, explosion-proof, and strong environmental adaptability. |
