37mm Brushless DC Gear Motor, 12V, 1:6 Gear Ratio, with PWM Speed Knob

24V Brushless Motor Kit, with Mounting Bracket & Speed Controller, for Automation

Product Overview

The CHR-GM37-BL3650 brushless DC gear motor is a compact, high-efficiency motor designed for continuous operation in automation and robotics projects. It features built-in PWM speed control, reversible direction, and multiple gear ratios, making it ideal for electric doors, PTZ cameras, and industrial equipment.

Key Features

  • Built-in PWM Speed Control: Sealed potentiometer knob offers stepless speed adjustment (10%~ duty cycle), compatible with 10-50KHz PWM signals.
  • Dual-Voltage Compatibility: Supports DC 12-24V operation, with optimized performance at both voltages.
  • Multiple Gear Ratios: Choose from 1:6 to 1:810 to customize speed and torque for your project.
  • Reversible Direction: Simple wiring control for clockwise/counterclockwise operation.
  • Durable Construction: 37mm diameter body, 6mm D-shaped shaft, and brushless design for long service life.
  • Optional Mounting Bracket: Available with a bracket for easy installation in fixed applications.
