Overview
These CHIHAI MOTOR 480 brushed DC motors offer distinct numbered windings, shaft lengths, magnet materials and pinion configurations for compatible hobby mechanisms. Select the exact configuration using its dimensions and electrical requirements. The pinion puller and two-piece shaft-sleeve pack are separate accessories and contain no motor.
Specifications by Configuration
Speeds are voltage-specific references. Overall length includes the output shaft and pinion where fitted. Motor body length is45.5mm and width reference29.5mm in the model cards. The standard gold/blue/red M150 envelope reference is29.5×25.2×88mm; it does not describe the100mm extended or74mm short-shaft configurations.

Standard M150 Long-Shaft Performance
The following11.1V operating points apply specifically to long-shaft No8 Gold,No6 Blue andNo7 Red M150 configurations. They do not apply to No5/99 N52 motors, other windings, or the short-shaft96–99 models. Torque units differ between the gold and blue/red tables.

Stall figures are reference limits, not permitted operating conditions. Maximum-output-power and maximum-efficiency values are distinct test points, not continuous-duty ratings. Use wiring, switching and a power supply suitable for startup/load current; stop if the motor stalls or overheats.
Electrical and Installation Guidance
Use the selected model's voltage and speed references. Most numbered configurations provide7.4V and11.1V data; only No44 also specifies a14.8V/25000rpm operating reference. Do not apply14.8V to other models by association. High-speed41/43 references favor7.4V operation to limit heating. Check shaft length, pinion type and mating-gear fit before installation; similarly named hobby platforms do not establish universal compatibility.
Electronic trigger/controller compatibility varies. Mechanical-switch use is recommended for high-speed7/41/42/43/46/47/48/97 configurations; avoid frequent active braking or rapid single-cycle reversals that overheat the motor or switching electronics. Models with stated electronic-control compatibility still require a correctly rated controller and wiring.
For higher-demand5/6/7/40/41/42/43/45/46/96/97/98/99 installations, the model guidance calls for a high-current connection such as XT30 and adequately sized wiring; several references specify at least1mm² conductors. A connector alone does not establish system current capability. No47/48 use2.8mm terminal connections; verify the actual connector and avoid soldering damage. Disconnect power before wiring or changing the pinion. Never force a misaligned gear or operate continuously stalled.
Accessory-Only Options
- Motor Pinion Puller Only:one gear-removal tool; motor and pinion are not included. Verify the tool fits the pinion and shaft.
- 32.5mm Bearing Shaft Sleeves –2PCS:two bearing-support sleeves;32.5mm length and9mm diameter reference. This option contains no motor. Verify bore, cup and motor-fit dimensions before installation.
What's Included
One motor of the selected numbered configuration, with the pictured pinion where specified, or the separately selected pinion puller or two-piece sleeve pack. Motor+tool or motor+sleeve bundles are not implied. Power supply, controller, complete mechanism and other motors in comparison images are not included. Standard M150 motor mass is approximately150g and its boxed reference185g; other configurations and packaging vary.
