The additional6000RPM performance charts are reference data, with8–1154RPM output speeds. Those reference configurations are not selectable sale options.

Built-in brushless driver and wiring

The supplier specifies the five-wire version without braking as standard. Six-wire brake diagrams are reference information; request and confirm the brake version before ordering. It is not a separate selectable variant here.

Wire	Function
Red	Motor DC supply positive (+)
Black	Supply negative / signal ground
Yellow	FG speed output: 6 pulses per motor revolution before reduction
White	Direction control
Blue	PWM speed control
Green (six-wire version only)	Brake input; connect to ground to brake

Never reverse red/black supply polarity. Change direction through the white control input, and stop the motor before switching direction. The supplier diagrams disagree on CW/CCW labels; white open and white low select opposite directions, and output-shaft direction also depends on gearing. Do not rely on the generic polarity-reversal text found in some source images.

Yellow FG is an open-collector speed-feedback output, not a controller input or a quadrature position encoder. The supplier specifies a 4.7 kΩ pull-up to 5V and a maximum output current of 3mA. Pulses per gearbox revolution depend on reduction ratio. Do not connect yellow FG to the illustrated speed controller.

The source lists 0–5V control signals and PWM frequency of 10–60kHz, with 20–30kHz recommended. Keep control inputs separate from the 12V/24V motor supply. For the six-wire reference, the blue input at ground commands full speed and green at ground applies braking. Follow the wiring diagram for the supplied version.

Use matching DC voltage and a compatible brushless control board. Do not connect the motor directly to AC. Reducing speed may reduce available torque. Avoid overload and stall.

Supplier data notes

Dimensions and weights are approximate. Power, current, noise, temperature and continuous-duty figures are supplier-listed; measurement conditions are not fully specified. Where power and current do not agree, confirm actual supply demand rather than assuming the listed wattage is verified electrical input power. Stall torque is a limit, not a continuous operating rating. No waterproof rating is supplied.

Package contents

One motor in the selected configuration, plus only the accessories named in the selected Package option. Supply plug type and complete controller ratings are not specified; confirm compatibility for your installation.
