24V Brushless DC Motor BLDC3650 Speed Compact Design with Precise Hall Feedback

Model BLDC3650 Brushless DC Motor Compact, speed brushless motor with builtin Hall sensor drive and integrated speed feedback. Designed for small electric drive applications where size, controllability, and reliable commutation are required. Key features and benefits Compact footprint: motor body measures 35 by 25 by 9 mm with an outer diameter near 36 mm, making it suitable for tight installations. Shaft length is 9 mm from the casing plane to the shaft head. Precise commutation and feedback: builtin Hall sensor drive and Hall FG output provide reliable rotor position sensing and a pulsed tachometer signal for closedloop control or RPM monitoring. Wide supply options and strong performance: supports 12 V or 24 V operation. At 24 V the motor reaches up to 8300 rpm with maximum output power in the 30 to 40 W range. Fast and smooth speed control: accepts a 0 to 5 V PWM speed input with recommended PWM frequency of 10 kHz. Duty cycle maps linearly to speed from low to . Direction and braking control: simple digital direction input and a brake function allow easy system integration without additional hardware. Standard shaft and wiring: 3.175 mm diameter shaft (1 8 inch) and a 27 cm cable lead simplify mechanical coupling and electrical connections. Electrical and performance specifications Model: BLDC3650 Rated supply voltages: 12 V and 24 V Noload current: up to 230 mA at 12 V; up to 300 mA at 24 V Noload speed: approximately 4150 rpm at 12 V; approximately 8300 rpm at 24 V Rated torque: 50 g·cm at 12 V; 100 g·cm at 24 V Rated speed: about 3400 rpm at 12 V; about 6800 rpm at 24 V Rated current: up to 0.8 A at 12 V; up to 1.6 A at 24 V Peak drive protection: nominal power rating near 30 W; drive protection current 3.0 A Mechanical size: motor body 35 x 25 x 9 mm, outer diameter dimension 36 mm Shaft: diameter 3.175 mm, length 9 mm from casing plane to shaft head Internal construction: brushless stator with quadrupole magnetic rotor and sixslot structure Wiring and control signals Black wire: power negative. This is the common ground for motor and control signals. Red wire: power positive. White wire: direction control (CW/CCW). Tie white to the negative line to reverse rotation. Yellow wire: FG output. Pulsed Hall signal for speed measurement and monitoring. Blue wire: PWM speed control input. Accepts 0 to 5 V pulse width modulation for speed regulation. Connecting the blue PWM line to power negative engages the brake immediately. PWM speed control guidance Use a separate PWM controller supply if preferred; motor power supply and PWM controller supply can be independent but must share a common ground with the motor negative (black wire). Recommended PWM amplitude: 0 to 5 V logic level. Recommended PWM frequency: around 10 kHz. Duty cycle behavior: below approximately 10 percent the motor will be effectively static; increasing duty from about 10 percent to 100 percent increases motor speed from minimum to maximum. Ensure the PWM controller ground is connected to the motor negative to provide proper reference and stable control. Important cautions Do not reverse the power polarity. Reversing the positive and negative supply will damage the drive board and the motor. Do not connect the power negative directly to the FG output line. Shorting the FG line to the negative supply can damage the drive electronics and the motor. Observe rated currents and the drive protection current to avoid overloading the controller. Practical applications Small robotics and automation: compact form factor and precise Hall feedback make this motor suitable for micro robotic joints, gimbal controls, and small actuators. Model vehicles and drones: size and speed characteristics suit micro RC vehicles, UAV propulsion for lightweight platforms, or ancillary systems such as camera gimbals. Small pumps and cooling fans: controllable speed and brake function enable variable flow pumps or compact fan assemblies where compact motor size and PWM speed control are required. What makes this motor stand out Integrated Hall sensor drive simplifies controller requirements and improves reliability of commutation. Compact dimensions and standard shaft size allow flexible mechanical integration. Clear wiring functions for direction, braking, and FG feedback reduce system complexity. Robust speed control via 0 to 5 V PWM with recommended 10 kHz frequency delivers smooth, repeatable performance.
