CHIHAI CHF-480A/WA Brushed DC Motors –24 Numbered Configurations

Overview

Choose a CHIHAI MOTOR 480-size brushed DC motor by its numbered configuration. The CHF-480A/WA range includes ferrite, N35/N35H and N52 magnet designs, multiple speed windings, and different end caps and cooling cases. A fitted pinion and spring are shown on the individual motor photos; the selection is one motor, not the multi-motor comparison set.

Features

• Ball-bearing construction, metal pinions and replaceable carbon-brush style rear assemblies.
• Enclosed, eight-hole and six-slot cooling cases vary by selection.
• Numbered configurations separate high-torque, medium-speed and high-speed choices.
• Electronic trigger/chip-control suitability varies; select a mechanical-switch configuration where indicated.

Configuration Guide

No. 17 also has a 14.8 V reference speed of 20,000 rpm, with suggested ratios 16 / 18 for 18:1 / 16:1 gear sets. No. 1 is labelled “low speed” relative to this series; the numerical reference is 19,000 rpm at 11.1 V. Speeds are reference operating values, not guaranteed loaded speeds. Select by the numbered photo and verify the actual installation.

Specifications

No. 22 and No. 23 are shown with the shorter arrangement and a labelled overall length of80 mm. The dimensional reference is not a guarantee of fit for every gearbox; compare your selected motor photo and measure the mounting space before installation.

M120 / M140 / M160 Performance Reference

The following 11.1 V curves are reference data for the named series constructions. They do not rate every numbered option; stall and maximum-output conditions are not continuous operating limits.

Gearing and Electrical Installation

These ratio figures are application references for compatible 18:1 and16:1 hobby gearbox gear sets, not supplied reduction gears or a universal compatibility promise. No. 20 is not recommended for13–16:1 high-load ratios. No. 25 is not recommended below16:1. No. 26 is intended for suitable18–20:1/80% or100% rack applications; avoid an unsuitable21:1 setup. No. 27 requires a suitable90% or100% rack arrangement; an85% rack may lead to gear interference.

For the illustrated high-current M160 setup, use a genuine high-discharge battery: an18650 cell capable of at least20 A (30 A recommended), or a1200 mAh polymer pack rated25C or higher. Use an XT30 connector and at least1.0 mm² heat-resistant wiring for the associated wiring assembly. The higher-output N52/fast configurations can require stronger power delivery; No. 26 specifies high-discharge25C or above. These are application recommendations, not included battery or wiring accessories.

Check polarity at the motor terminals before connecting power. Use a correctly rated switch/controller, suitable fuse protection and a secure insulated installation. Avoid prolonged stall or overload. A motor marked for electronic control still needs a compatible controller; the motor itself does not include a control board.

Applications

Replacement or custom hobby gearbox drive assemblies that accept the selected480-size motor geometry, pinion and electrical load. T238/electronic-control and mechanical-switch suitability depends on the chosen configuration and matching gearbox; no universal drop-in fit is implied.

What's Included

One selected numbered motor in the configuration shown by its bound photo. A gearbox, battery, controller, connector and wiring assembly are not included.

FAQ

Can I select speed as a separate option?

Each speed, magnet and construction combination belongs to a fixed numbered motor. Choose the actual configuration; a separate voltage or speed combination is not manufactured by this listing.

Are all versions suitable for electronic control?

No. Nos.11,12,13,18,24 and26 recommend mechanical-switch operation; the remaining options are labelled for chip control, subject to matching controller and load.
