SPIDER Automation 3-Phase Brushless Motor Controller | 15–36V 500W Sensorless BLDC Driver | For High-Performance Motor Control
Description
The SPIDER Automation 3-Phase Brushless Motor Controller Driver Board is a compact electronic controller designed for three-phase sensorless brushless DC (BLDC) motors. It operates from a 15–36V DC supply and supports motor power up to 500W with a specified current capacity of up to 15A.
The controller provides multiple speed-control methods, including voltage-based speed regulation, single-chip control and PWM speed regulation. This flexibility allows the board to be integrated into different motor-control architectures depending on the control requirements of the application.
Integrated overload protection, locked-rotor protection and over-current protection provide protection against several abnormal operating conditions. These features make the controller suitable for embedded motor-control systems where compact size, adjustable speed control and protection functions are required.
As a sensorless BLDC controller, compatibility and driving performance can vary depending on the characteristics of the specific three-phase motor. If the motor exhibits startup jitter, unstable speed, excessive no-load current, reverse-rotation problems, reduced efficiency or difficulty starting under load, the resistance and capacitance values on the driver board may need to be adjusted according to the actual motor characteristics.
Proper adjustment should therefore be carried out during system development and testing to obtain stable startup, suitable speed regulation and the required operating performance for the selected motor.

Motor Compatibility & Drive Adjustment
This controller is designed for three-phase sensorless BLDC motors, but the supplied product information specifically indicates that it is not universally suitable for every three-phase sensorless brushless motor without adjustment.
Motor and controller characteristics can affect startup and running performance. Depending on the motor, the system may exhibit startup vibration or jitter, unstable speed, excessive no-load operating current, reverse-rotation behavior, reduced efficiency or difficulty starting when a load is connected.
When such conditions occur, the resistance and capacitance values of the driver circuit can be adjusted according to the actual motor characteristics to obtain a more suitable driving response. Motor-controller compatibility should therefore be verified under the intended operating conditions before final system deployment.
Protection Functions
- Overload Protection: Provides protection during excessive motor-load conditions.
