M1 sensorless ECM motor control board with capacitors, connectors and screw terminals

Product Description

M1 is a sensorless external ECM motor control board designed for HVAC fan, blower and fan coil applications. As a compact ECM / BLDC motor driver, it supports stepless 0–10V speed control, 3-speed control and RS485 communication, providing flexible speed control for different HVAC operating requirements.

Unlike a universal motor controller, M1 can be programmed and matched to specific ECM / BLDC motors according to motor characteristics, target RPM, airflow and application requirements. A built-in 6-position DIP switch provides motor rotation setting and multiple preset speed configurations, making the board suitable for customized HVAC OEM/ODM projects. M1 can be supplied as part of a matched ECM motor + external driver solution for fan coil units (FCU), HVAC fans, blowers and other air-moving equipment.

Technical FAQ

Can M1 work with my existing ECM or BLDC motor?

Yes. Compatibility is evaluated according to the motor voltage, power, electrical characteristics, target speed and HVAC application requirements.

Does M1 require Hall sensors?

No. M1 uses sensorless ECM / BLDC motor control and does not require Hall sensor feedback from the motor.

What motor power does M1 support?

M1 is designed for compatible HVAC ECM / BLDC motor applications up to 80W, subject to motor matching and application verification.

What control options does M1 support?

M1 supports 0–10V, 3-speed and RS485 control. Availability and settings can be configured for the project.

Can the firmware be customized for my motor?

Yes. Motor parameters, startup behavior, speed range and control logic can be matched to the motor and HVAC application.

Can I request an M1 sample for testing?

Yes. Send us your motor information and application requirements so our engineering team can evaluate compatibility and prepare a matched sample.
