Overview
The CHIHAI MOTOR CHP-36GP-BLDC3650 is a 36mm brushless DC gear motor combining an all-metal planetary gearbox with a built-in Hall driver. Choose the 12V or24V motor, reduction ratio and accessory package independently. An8mm D-shaped shaft provides a compact mechanical interface for automation and motion mechanisms.
Configuration Guide
Ten nominal reduction ratios are available:3.7:1,5.2:1,14:1,19:1,27:1,51:1,71:1,100:1,139:1 and264:1. Select Motor Only, Motor + Bracket, Motor + Brushless Controller, or Motor + Brushless Controller + Bracket. Each package includes one motor and only the named accessories. No power supply is included.
Features
- Internal Hall driver for brushless commutation, with direction, speed-control and FG feedback leads.
- All-metal planetary transmission and ball-bearing shaft support.
- 8mm D shaft; gearbox length varies with ratio.
- Optional mounting bracket and compatible brushless speed-control board.

The rated operating points and maximum allowable gearbox load are separate limits. Entries marked “max” are the maximum permissible gearbox load of60kgf·cm (approximately6.0N·m), not a promise of rated continuous torque. Avoid overload and stalled operation. Maximum power values are references, not a continuous-duty rating. Performance for3.7:1 and71:1 is not specified here; do not infer it from adjacent ratios.
Overload protection reference: sustained current above3.0A interrupts operation; disconnect and reconnect power after correcting the overload. This protection is not a normal operating target.
Wiring and Control
| Lead | Function and connection |
|---|---|
| Red | Motor supply positive; use the selected12V or24V voltage. |
| Black | Supply negative and signal ground. |
| White | Direction control: open and connected to black/GND select opposite directions.0–5V input; high≥2V, low≤0.2V. Confirm output-shaft direction on the actual gearbox. |
| Blue | PWM/speed input,0–5V; analog speed-reference range1.2–3.3V. Use the five-wire arrangement for speed regulation. |
| Yellow | FG open-collector speed-feedback output,6 pulses per motor revolution before reduction; not a quadrature encoder. |
FG reference:5V pull-up through10kΩ; high output≥4V, low≤0.6V, maximum sink current5mA. Pulses per output-shaft revolution depend on the reduction ratio. The12V termination reference specifies±10% supply tolerance; it is not a24V supply tolerance specification.
Never reverse red/black power polarity. Keep motor supply voltage away from FG, PWM and direction inputs. Do not short the supply negative against the FG or speed lead during wiring; incorrect connections can damage the internal driver. Direction changes use the white lead, not reversed power. Stop before changing direction. The three-wire basic arrangement uses power and direction; blue/yellow provide additional control and feedback in the five-wire arrangement. No braking function is promised.
Applications
Use the selectable reduction ratio to match speed and load in small automation mechanisms, inspection equipment, smart machines and robotics projects. Check continuous load, mounting, shaft fit and electrical compatibility for the actual installation. Example robots and machines are not included.
What's Included
One motor in the selected voltage and ratio; one mounting bracket when the selected package includes Bracket; one brushless speed-control board when it includes Controller. The bracket and controller are not included with Motor Only. Power supply and application equipment are not included.
