R88D-GT02L

The R88D-GT02L is a two-phase stepping motor driver board, which is a part of the motor driver modules. It provides current control and is designed to control, and provide power to two-phase (four-wire plus unipolar) stepping motors. It is the ideal choice of the automation system to expand the saving and high precision of the electrical power. This article will introduce the application field and working principle of the R88D-GT02L motor driver board.

Application Field

The R88D-GT02L has a diverse application range, from the simplest home products to the most sophisticated industrial machinery. It can be used in industrial robots, office automation systems, medical equipment, machine tools, X-Y plotters, textile machinery, chemical process control and other machines. With its high precision, linear response, fast speed and low power consumption, the R88D-GT02L is a efficient combination of motor driver board, motor and gearing.

Working Principle

The R88D-GT02L operates at high voltage (24V DC) and low current (2A). Working on the principles of sinusoidal current control, the motor produces high torque throughout its speed range. The driver board takes a high frequency pulse as input via the pulse input pins and converts it into a precise motor rotation, outputted to the two-phase stepping motor.

The driver board contains two power transistor circuits, featuring such functions as output current limit and protection against over temperature and overvoltage. The R88D-GT02L can be used with either unipolar or two-phase type stepping motors. It also has the ability to reverse the direction of rotation in response to the input signal. This allows it to be used in applications where constant speed control is needed, such as machine tools, printing presses and plotters.

The R88D-GT02L is engineered with high quality components and is suitable for a wide range of industrial applications requiring precise, linear control or high-speed operation. Its simple structure, easy installation, and reliable performance make it the ideal choice for motor driver boards and modules.
