Variable frequency drive (VFD) is a kind of power control equipment which uses frequency conversion technology and microelectronics technology to control AC motor by changing the speed of motor. The VFD is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), drive unit, detection unit, micro processing unit, etc. VFD motor is a combination of variable frequency drive and three-phase motor to be used with AC 50Hz/60Hz power supply system. The VFD motor can adjust the speed of motor under various load conditions, completely eliminate the mechanical and electrical shocks and prolong the service life of mechanical equipment. It also works to protect against overload, overvoltage, undervoltage, phase loss and overheating.

Types of Variable Frequency Drive Motor

Flame Proof Asynchronous VFD Motor

The power rating range of this kind of VFD motor is from 55kW to 3000kW and it can be designed as per IP 56 or higher which is able to withstand a certain degree of flooding.

PM Integrated VFD Motor

PM integrated VFD motor combined VFD and motor,can supply a big torque even in low speed.it can output most of VFD/motor parameters and curves to distribute control system.

High Ingress Protection VFD Motor

High Ingress Protection VFD motor is mainly used in excavators in the field of construction machinery, port bucket wheel stacker-reclaimer, and etc.

Flameproof Permanent Magnet Motorized Pulley

The pulley is a kind of motor with is used for conveyor. Voltage is from 380V to 1140V and power rating is less than 300kW.

Application of the VFD Motor

The VFD motor can run in the explosion environment. Flameproof and intrinsically safe high-voltage integrated VFD Motor is a highly integrated product of the motor and the drive. It is widely applicable to belt conveyors, loaders, AFC's, emulsion pumping stations, and other equipment used in underground coal mining to achieve a soft-start under heavy load and dynamic speed control. CCS can offer a wide range of VFD motors for different scenarios, including VFD rated motor, VFD multiple motors, and other VFD compatible motor.

How to Select a VFD Motor

Choose the appropriate structure form of protection grade motor according to the application place.

Choose the appropriate power and voltage level according to the responsible ability.

According to the environmental temperature, humidity, above seal level, dust and gas conditions, special requirements such as explosion prevention are selected.

Choose a strong manufacturer to ensure the material quality and production process to the maximum extent.
