220V 250W 3-Phase Brushless Motor Controller, Sensorless FOC, PWM Speed Control

FOC Chord Wave Motor Drive Board 220V 250W 3-Phase Brushless Permanent Magnet Synchronous Motor Controller without Hall Sensors Why this drive module helps you - Ready-to-use FOC sensorless control reduces development time and debugging effort by providing a complete core algorithm and software base for rapid secondary development. - Compact, high-efficiency hardware driven by a 32-bit kernel MCU SNR8652M for reliable real-time control and easy simulation during development. - Built-in protections and multiple control interfaces let you integrate the module into industrial and commercial systems with confidence. Key features and functions - Field Oriented Control sinus wave drive with sensorless operation, supporting zero-speed closed-loop start and stable low-speed performance. - Non-inductive observer layer and back-EMF start algorithm for reliable operation without Hall sensors. - Phase compensation algorithm and PID closed-loop speed control with an optional power-limited PID mode. - Start-in-windback algorithm, stall protection, and controlled start/stop with forward and reverse direction control. - Multiple control interfaces: onboard potentiometer 0 to 5V, PWM speed input (frequency 1 to 20 kHz, duty 0 to 100 percent), and reserved UART serial port for custom control development. - FG speed feedback interface for RPM calculation: RPM = FG frequency in Hz times 60 divided by pole count. - Direction interface: open for clockwise, short to GND for counterclockwise. - Integrated LED indicators for standby, running, and fault states for quick status checks. - Onboard 433 MHz wireless receiver reserved for optional remote control functionality. - Onboard boot/burn interface for firmware updates. Protection and reliability - IGBT overtemperature protection. - Phase loss detection. - Stall and block protection. - Overcurrent protection. - Overvoltage and undervoltage protection. Mechanical and electrical specifications - Working voltage: 220V AC. - Maximum supported drive power: up to 250W with forced cooling using the supplied heatsink. - For motors under 50W, the standard heatsink and normal ventilation are typically sufficient without forced cooling. - Module dimensions: 118 mm length x 72 mm width, board thickness 1.6 mm. - Standard heatsink included with the module. What makes it stand out - Sensorless FOC with a completed core algorithm allows fast integration into product prototypes and production devices. - Small footprint with an integrated heatsink and multiple I/O options reduces the need for extra components. - Broad protection set and flexible control interfaces make it suitable for diverse high-pressure and high-load applications. Practical application examples - High-pressure water pump drive: precise speed control and strong protection for agricultural or cleaning systems requiring stable pressure and reliable starts. - High-pressure HVAC or industrial ventilation: efficient 3-phase motor control for fans and blowers in enclosed equipment with variable speed demands. - High-pressure food processing equipment such as soymilk or pasteurizing machines: sensorless startup and closed-loop speed regulation for consistent processing results. What you get - Motor driver board with the described features and interfaces and a standard heatsink for cooling. Note - Item color may vary slightly from images due to lighting and screen differences. - Allow 1 mm to 10 mm tolerance for manual measurements.
