GFR4B10300 (also known as “GFR4”) is a high-speed, single phase electric motor drive product, developed and produced by Shenzhen Gonggong Electric Co., Ltd. It is primarily designed for large-power motor applications, such as pumps, fans, and compressors, and is applicable to a wide range of motor sizes and speeds. The GFR4B10300 has a unique combination of features that make it ideally suited for high-performance, high-efficiency applications.

The GFR4B10300 is designed for AC motors with a rated power output of 3Kw and a rated speed of 10,300 rpm. It comprises three stages of full-bridge control, active frequency control, over voltage protection, embedded current sensing, and pulse width modulation (PWM). Its main features are the ability to accurately control the motor\'s speed, as well as offering a wide, adjustable output current range. This provides the user with a high level of control over motor speed and torque output.

The GFR4B10300\'s main application fields are in the control of variable speed motors, such as those used in pumps, fans, compressors, and other industrial applications. It is especially useful in applications where the speed of the motor must be continually adjusted, such as climate control systems, variable fan speed applications, and load leveling for large pumps. The GFR4B10300 is also suitable for other motor types, such as three-phase motors and stepper motors.

The working principle of the GFR4B10300 involves the use of three stages of full-bridge control and active frequency control. The first stage is a pulse width modulation (PWM) control, which is used to accurately adjust the motor speed. This stage is also responsible for the speed signal processing and provides over-voltage protection. The second stage is the frequency control stage, which provides a wide, adjustable range of output current. The third stage is an embedded current sensing stage, which is responsible for monitoring the motor\'s load and adjusting the output power accordingly.

The GFR4B10300 is a powerful, high-performance motor drive product, ideal for a range of application areas. With its wide range of features and capabilities, it is highly suitable for applications in variable speed control, over-voltage protection, and load balancing in industrial and commercial environments.
