Overview
Choose a CHIHAI MOTOR miniature brushed DC motor by its winding, voltage and intended duty. The listing includes 50TPA and 30TPA 130WH configurations plus a separate 132WH-23TPA option. Their speed, housing and performance references differ.
Features
- Compact high-speed motor configurations with voltage-specific selector choices.
- The 50TPA reference uses a round 2 mm shaft and front/rear ball-bearing support.
- Insulated enamelled copper windings, reinforced commutator connections and a balanced armature in the illustrated 50TPA construction.
- Model-specific motor photos remain shared where the source configurations share the same image.
- Motor-only and optional spade-lead packages.

Configuration Guide
| Configuration | Speed reference | Important scope |
|---|---|---|
| 50TPA,11V | 42,000 rpm | 11.1V performance table below; nominal selector label is11V |
| 50TPA,7.4V | 27,000 rpm | No separate loaded performance table provided |
| 30TPA,11.1V | 72,000 rpm | Short runs recommended≤10 seconds |
| 30TPA,7.4V | 47,000 rpm | Short runs recommended≤10 seconds |
| 132WH-23TPA | 11.1V /70,000 rpm marking | Separate body/vent design; do not apply50TPA dimensions or performance by default |
The 30TPA motor is not intended for continuous running. Use short runs, with individual runs of 10 seconds or less recommended. Select the supply for the chosen voltage and allow for the required current under load. The 150°C figure describes the referenced magnet material; it does not establish an allowable operating temperature for the complete motor.

The 30TPA reference lists a dynamic resistance of 0.15 Ω. These are separate model/voltage test points, not continuous ratings or specifications for every configuration. Stall current, maximum-output current and no-load current describe different conditions. Avoid stalling and use suitable wiring and switching equipment.
Mechanical Dimensions and Connection
The dimension drawing applies to the illustrated 50TPA motor. Check mounting-hole spacing, shaft projection, housing outline and rear-terminal clearance before installation. The red-marked terminal is positive in the illustrated terminal view; the opposite terminal is negative. Confirm the actual selected motor before wiring.
Applications
For compact toy and model mechanisms, suitable flywheel drives and small-car mechanisms when the selected motor's speed, duty, current and mechanical fit match the application. A high-speed winding is not a universal replacement for another motor.
What's Included
| Selected package | Contents |
|---|---|
| Motor Only | 1 × selected motor |
| Motor + Spade-Terminal Leads | 1 × selected motor and the named spade-terminal lead set |
Power supplies, batteries, controllers, wheels and application equipment are not included. The corresponding winding photo may show a representative voltage marking; the selected option determines the configured voltage/speed reference.
FAQ
Can the 30TPA motor run continuously?
No. It is intended for short runs; individual runs of 10 seconds or less are recommended.
Does the 150°C magnet reference mean the complete motor can run at 150°C?
No. It is a magnet-material heat-resistance reference, not a complete-motor operating-temperature rating.
Do the 50TPA performance and dimensions apply to 23TPA?
No. The 23TPA option has its own motor photo and marking. Check its actual dimensions and operating requirements separately.
Does Motor Only include connection leads?
No separate lead set is included. Choose the package that explicitly names spade-terminal leads.
