R88D-KN02L-ECT-R Motor Driver Boards, Modules

The R88D-KN02L-ECT-R motor driver board or module is designed to power a motor whose drive control utilizes a Pulse Width Modulation (PWM) input. This type of driver board allows for a high-speed motor control with low power consumption, along with smooth operation and precise speed and torque control while protecting the motor from damage due to overcurrent. The R88D-KN02L-ECT-R motor driver board or module is applicable to a wide range of applications, from direct drive applications for the CNC machines to robotics and digital signage.

Application Field

The R88D-KN02L-ECT-R motor driver board or module is suitable for a wide range of applications, including the following:

• CNC Machines
• Automatic Door Openers
• Robotics
• Linear Motion Control Applications
• Electronic Security Devices
• Digital Signage and Display Systems
• Power Tool Motor Control

This type of driver board is suitable for powering motors with a power range from 0.14kW to 3.7kW. The integrated circuit of the driver board can precisely control the motor\'s speed, torque, and current, providing a smooth and precise operation. In addition, the “current-limiting” feature can protect the motor from overcurrent and overvoltage, which helps prolong the motor’s service life.

Working Principle

The R88D-KN02L-ECT-R motor driver board or module utilizes a Pulse Width Modulation (PWM) input signal to precisely control the motor. The motor driver board consists of an integrated circuit (IC) and a rectifier bridge. The IC provides the motor driver with an adjustable output voltage to precisely control the motor speed, torque, and current. The PWM input signal is connected to the IC, which controls the pulses applied to the rectifier bridge. The rectifier bridge converts the PWM signal into a motor current, which is then applied to the motor’s windings.

The integrated circuit of the driver board includes a current-limiting circuit that can be adjusted to protect the motor from overcurrent or overvoltage. The current-limiting circuit generates an interruption in the power flow to the motor windings, which reduces the damage caused by overcurrent or overvoltage. In addition, the driver board also includes a thermal protection circuit that will reduce power and interrupt motor operation if the driver board temperature exceeds the upper limit.

The driver board can also be equipped with an external variable-speed control, which allows for additional capabilities such as controlling multiple motors, setting motor speeds, and setting the current-limiting threshold. A variety of communication protocols are also supported, including CANbus, RS-485, and EtherCAT. This allows the driver board to be integrated seamlessly into a variety of motor control systems.

The R88D-KN02L-ECT-R motor driver board or module provides a powerful and precise motor control system that is suitable for a wide range of applications. The integrated current-limiting and thermal protection circuits ensure the safety and reliability of the motor control system.
