VFD MOTOR

What is a VFD compatible motor? 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 motor with integrated 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 rated 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. And the variable frequency drive motor 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

VFD for Synchronous Motor Frequency Converter

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.

What is a vfd motor?

A vfd in motor is a motor that is powered by a variable frequency drive (VFD), also known as an adjustable frequency drive (AFD), variable speed drive (VSD), or inverter drive. A VFD motor is typically an AC induction motor that is connected to a VFD, which allows for precise control of the motor's speed and torque.

The VFD works by converting the fixed frequency and voltage of the power supply into a variable frequency and voltage that is supplied to the motor. This allows the speed of the motor to be adjusted without changing the frequency of the power supply, which in turn can save energy and reduce wear and tear on the motor.

What Motors Can be Used with VFD?
VFD motors are used in a wide range of applications, such as HVAC systems, industrial machinery, and even electric vehicles. They offer several benefits over traditional fixed-speed motors, including improved energy efficiency, reduced wear and tear on equipment, and greater control over the motor's speed and torque.
Some of the most commonly used motors with VFDs include:
AC Induction Motors: These are the most common type of motor used with VFDs, and are well-suited for variable speed applications.
Permanent Magnet Motors: These motors have high efficiency and are often used in high-performance applications.
Synchronous Motors: These motors have a constant speed and are often used in applications where precise control is required.
Brushless DC Motors: These motors are often used in high-speed and high-precision applications.
VFD Motor Efficiency
Motor efficiency does change as speed and torque change and is also affected by voltage harmonics present in the VFD motor output. The magnitude of losses due to voltage harmonics will vary with the motor design. VFD motor efficiency decreases with decreasing motor load. The decline in efficiency is more pronounced with VFD motor of smaller horsepower ratings.
How Does a VFD Change Motor Speed?
A variable frequency drive controls the motor speed by using PWM (Pulse Width Modulation) to alter the power supply frequency that's fed to the motor. The first step in this process is to convert the AC supply voltage into DC by the use of a rectifier. DC power contains voltage ripples which are smoothed using filter capacitors.
Changing Motor Rotation on a VFD
It is usually easy to change the direction of rotation with the VFD itself. Most VFD's have a simple toggle command for forward and reverse. Switching two of the power leads coming out of the VFD can solve the problem of which the motor is shut down and later restarted, it will restart running backwards again.
Application of the VFD Motor
The VFD motor can run in the explosion environment. Flameproof and intrinsically safe high-voltage ingress protection of 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 for synchronous motor, VFD rated motors, VFD multiple motors, and other VFD compatible motors.
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.
