CHIHAI 480 Short-Shaft Brushed DC Motor, Models 81–95

Overview

The CHIHAI MOTOR 480 short-shaft brushed DC motor range offers 15 numbered configurations, 81#–95#, with model-specific winding speeds, magnet materials, end caps and pinions. Choose the exact numbered model and check its electrical and mechanical requirements before fitting.

Features

• Short 15.5 mm shaft projection and 74 mm overall reference length.
• Ball-bearing support and dynamically balanced armature.
• NdFeB magnet options alongside the 93# ferrite configuration.
• CNC aluminum, nylon and PPS end-cap options with distinct vented or closed housings.
• Model-specific MIM D-bore steel or powder-metallurgy alloy pinions.

Specifications

Model and Speed Selection

The selector abbreviates nominal voltage as11 V; the numbered technical artwork specifies11.1 V. These speed references are configuration-specific and do not establish loaded speed or a universal continuous-duty rating.

92# additionally lists35, 000 rpm at 14.8 V.85# includes an internal cooling fan. Physical colors, labels, terminals and venting follow the selected option photo; a shared480 format does not make different windings interchangeable.

81# / CHF-480WA-8513G Performance at 11.1 V

This table applies to the 81# reference only. The other numbered motors have different windings and construction. Maximum-efficiency and maximum-output points are different conditions, and neither establishes a continuous-duty rating.

Stall current and torque describe a blocked rotor. Avoid stall and overload; choose the supply, wiring, switching path and cooling for the actual running load.

Electrical Connection and Installation

• Match shaft projection, pinion engagement, outline and terminal clearance before installation.
• Use a suitable high-current DC supply and switching system for the selected winding. Several numbered references specify an XT30 connection path and at least 1.0mm² conductors; verify the actual load and connection.
• For93#, use2.8 mm spade-terminal connections; avoid soldering directly to the motor terminals.
• High-speed motors can generate substantial heat. Reduce loading and provide cooling suited to the duty cycle.
• Speed reduces under load. Reducing motor drive speed can also reduce available torque; select by the actual mechanism requirements.
• Noise varies with speed and load. Avoid stalled operation, excessive loading and mismatched voltage.

Applications

For compatible compact hobby and model mechanisms requiring a 480-format brushed DC motor. Select by the numbered model, supply, mechanical fit and load. The motor format alone does not establish compatibility with a particular mechanism or controller.

What's Included

One selected numbered motor with its pictured shaft, pinion and spring arrangement. Alternative motors in comparison pictures are not a multi-motor package. The separately illustrated16-tooth gear set is an optional accessory and is not included in every motor option. Battery, controller, supply and external connection leads are not included.

FAQ

Do all 15 motors have NdFeB magnets?

No.93# uses wet-pressed ferrite; the other numbered configurations listN35H orN52 NdFeB as shown in the model table.

Can I apply the 81# current and torque table to every model?

No. It describes the CHF-480WA-8513G reference at 11.1 V; other windings have separate characteristics.

Is14.8 V specified for every option?

No. Only 92# has a 14.8 V /35, 000 rpm reference in its numbered artwork.

Are these the long-shaft480 motors?

No. These options use the 15.5 mm shaft-projection and 74 mm overall references. Check the chosen motor and pinion before installation.
