BL2406 Digital Brushless DC Motor Drive Controller 12-24VDC Max 8.0A 180W

This BL2406 digital brushless DC motor drive controller delivers up to 8.0 A of continuous output current and 180 W of motor power from a 12–24 VDC supply, supporting a wide speed range of 150 to 30,000 RPM. It features multiple speed control methods including analog 0–5 VDC and PWM input, along with built-in protection against overcurrent, overvoltage (30 VDC), undervoltage (10 VDC), and Hall sensor faults in a compact 60 × 45 × 33 mm housing. Its reliable performance and versatile control interface make it well suited to driving small BLDC motors in applications such as industrial automation equipment, robotics, medical devices, coffee machines, mixers, and other compact motor-driven systems requiring precise speed regulation and robust protection.

Key Features:

• Enable, direction, and brake input signals.
• Wide speed regulation range: 0-20000RPM.
• Supports deep functional customization. Specialized machine applications.
• Supports different application scenarios; the dynamic response of the driver can be customized.
• The driver features low self-loss, high efficiency, and low temperature rise, resulting in a small size and easy installation.
• Various comprehensive protection functions... Current limiting protection function to prevent motor damage caused by stalling.

Technical Specification

Digital Control Signal Ports

• DC+/DC-: DC voltage input terminal (DC10V~DC24V)
• U, V, W: Motor phase wires
• Hu, Hv, Hw: Hall signal wires
• VCC: Hall power +
• SV: External speed regulation. Leave floating when using internal speed regulation.
• F/R: Direction. Floating or high level indicates forward rotation; low level indicates reverse rotation.
• EN: Control signal enable terminal. High level stops; low level runs.
• BRK Brake. Low level for normal operation; high level stops.
• ALARM: Alarm signal output terminal

Interface Function Description

Start and Stop (EN)

• The motor runs automatically after the driver is powered on.
• Connecting the EN terminal and the DC- terminal can control the stop of the motor. (The control logic level can be reversed via the host computer).
• By connecting a switch between DC- and EN or using a PLC to control its on/off state, the motor can be switched between start and stop.

Quick Stop (BRK)

• The motor runs automatically after the driver is powered on.
• Connecting the BRK terminal and the DC- terminal can control the motor to brake and stop quickly. (The control logic level can be reversed via the host computer).
• By connecting a switch between DC- and BRK or using a PLC to control its on/off state, the motor can be switched between start and brake.

Direction Control (DIR)

• The motor runs automatically according to the DIR setting after the driver is powered on.
• Connecting the DIR terminal and the DC- terminal can control the motor's direction change. (The control logic level can be reversed via the host computer).
• By connecting a switch between DC- and DIR or using a PLC to control its on/off state, the motor's direction can be switched.

Note: Observing from the direction of the motor shaft, clockwise rotation of the motor shaft is forward rotation, and vice versa is reverse rotation.
