Overview

The CHIHAI MOTOR CHF-BL480 Entry Series is a compact brushless DC motor with integrated control electronics, a purple CNC aluminum-alloy housing and a steel bevel pinion. Choose a short or long shaft and one of four speed versions to match the available space and drive requirements of your hobby mechanism.

Features

Brushless construction avoids carbon-brush wear and brush dust.
Ball-bearing support and UH-grade neodymium magnet material.
Built-in controller with a 32-bit CPU and a specified 4 ms response.
Six low-resistance MOSFETs support short phase-current pulses up to 120 A for less than 200 ms; this is not a continuous input-current rating.
Integrated undervoltage, overtemperature, stalled-rotor and load-adaptive dynamic-undervoltage protection.
Fixed steel bevel pinion and spring shown in the product photographs.

Configuration Guide

Both shaft lengths are offered in every speed version below. Speeds are voltage-specific reference values, not guaranteed loaded operating speeds. Match the shaft length, pinion engagement, mounting space and electrical requirements before installation.

Performance Reference

In a reference test using an M90 spring and 13:1 gearing, 200 single cycles produced a reported grip-temperature rise of 6–8°C. This is a test-condition reference, not a maximum motor temperature or a guarantee for other loads. The advertised 90+ cycle-efficiency figure compares actual cycling rate with a theoretical rate calculated from motor speed and gearing; it is not electrical conversion efficiency. Low heat rise, rapid startup and low stopping resistance depend on the complete mechanism and operating conditions.

Installation and Use

Use a suitable DC supply for the selected motor. The 3–24 V range on the generic instruction sheet covers other motors and is not an operating range for this CHF-BL480.
Observe the marked positive and negative terminals. Verify wiring and test with temporary leads before permanent connection.
Avoid stalls and operation close to the mechanical load limit. Protection circuitry does not eliminate the risk of overload damage.
Actual speed decreases as load increases. Confirm the required torque and speed for the mechanism; no numeric torque rating is specified here.
Reduced speed can reduce available torque. Operating sound varies with speed and load.
Check pinion engagement and shaft clearance before running the motor.

Applications

For hobby and toy drive mechanisms designed around this motor's bevel pinion and short or long shaft arrangement. A 480-size name alone does not establish drop-in compatibility with a particular gearbox or device.
