Product Description
FOC Control Principle Overview:
This driver adopts Field-Oriented Control (FOC) technology to achieve precise control of current vectors and stator magnetic field orientation, resulting in minimal torque ripple, high efficiency, low noise, and fast dynamic response. Unlike traditional brushless ESCs that can only operate effectively at high speeds, the FOC controller provides smooth and accurate control across the entire speed range, including low-speed operation, ensuring stable and efficient motor performance under heavy-load conditions.

Product Features
Supports Multiple Control Signals and Modes
Compatible with a variety of control inputs including potentiometer, analog signal, PPM, RS485, CAN, and CANopen. Supports multiple control methods such as duty cycle speed control, torque control, closed-loop speed control, and closed-loop position (angle) control.
Supports Constant Speed and Constant Power
Provides Constant Torque (constant current) Output
The maximum start/load current and braking current can be configured independently. Supports overcurrent output for high-torque performance during startup or heavy-load operation. The motor can operate in a stalled condition for long periods under constant power or constant torque mode. Supports motor speed measurement and stall detection/limit-stop protection.
Multiple Protections for Safer Operation
Built-in temperature monitoring for the driver; configurable over-temperature protection; supports power supply voltage monitoring; configurable over-voltage and under-voltage protection thresholds.

Usage Notes
Driver – Precautions for Use:
1、This product is powered by a DC power supply. Please confirm the correct polarity of the power terminals before powering on.
2、Do not plug or unplug cables while the power is on. Avoid short-circuiting any cables during operation, as this may cause permanent damage to the product.
3、The driver is not sealed. Do not allow screws, metal debris, conductive particles, or flammable materials to enter the interior. Ensure proper moisture and dust protection during storage and use.
4、As the driver is a power device, ensure adequate ventilation and heat dissipation in the working environment.
Hub Motor – Precautions for Use:
1、The brushless motor uses electronic commutation, and each motor must be controlled by a dedicated controller. Do not attempt to control two motors with one single-channel controller. To control two motors simultaneously, use two single-channel controllers or one dual-channel controller. For systems with four or more motors, please contact us for technical support.
2、Dual-channel controllers do not support differential turning functions. If differential steering is required, you need to develop a microcontroller program to send different speed commands to the left and right single-channel controllers respectively.
