Dual Channel Intelligent Brushless DC Motor Controller KYDBL4830-2E

I. Overview

KYDBL4830-2E is an intelligent brushless DC dual channel motor controller. The brushless dual-channel motor driver can control two brushless DC motors at the same time. It adopts 32-bit high-performance MCU and advanced movement processing algorithm to realize internal electric differential function. The controller uses the Hall signal inside the motor as the rotor position feedback and works with the external incremental encoder (1000—2500 line) signal to control the movement of motor, realizing speed open-loop, close-loop modes, position mode and torque mode. It has two-way independent driver chip, two-way encoder processing chip, two-way Hall signal processing chip. Meanwhile, it has multiple failure alarm functions. It has two working modes: independent mode and mixed mode. Independent mode: It can realize fully independent control of two-way motor, and the control signal part is controlled by two-way input signals. Two-way brushless DC motor can control the speed and direction of motor, separately.

Mixed mode: It can realize the synchronous control (forward, backward, left and right rotation) of two brushless motors.

The control signal has as many as 8 modes (wireless remote control, rocker, potentiometer, analog quantity, frequency, pulse width, RS232, CAN bus).

Note: The bottom of controller shell has 4*Φ5mm holes for installation and fixing, and installation can be conducted in the horizontal direction.

Keep the controller away from dust and high temperature environment, and avoid unexpected contact. Keep sufficient space around the controller for ventilation and adjustment.

When fixing the controller, keep it from other heat sources. Ensure the controller works within the specified ambient temperature range.

Avoid to install the controller to devices excessively vibrating; if it is necessary, please take good vibration-proof measures.
