Description

1. Product Overview

The φ5mm Ultra-Micro Brushless Coreless Motor is a compact drive component developed for applications where installation space, low weight, and high rotational speed are critical. With a motor diameter of just 5mm and a weight of 2.6g, it is designed for integration into miniature electromechanical systems, wearable devices, UAV-related equipment, precision instruments, and other compact intelligent products.

The motor uses flexible printed circuit board (FPCB) winding technology combined with AI-optimized design to balance performance, cost, and manufacturability. Operating at a rated voltage of 6V, it delivers a no-load speed of 55,000 rpm and a nominal speed of 30,000 rpm, making it suitable for applications requiring high-speed micro-motion.

Developed by VAXOR, this ultra-micro motor is intended for engineers, OEMs, and product developers seeking lightweight drive components for space-constrained designs.

4. Performance Parameters Explained

No-Load Speed: 55,000 rpm

No-load speed describes the motor's rotational speed when operating without an external mechanical load under the specified test conditions. Actual speed decreases according to the connected load and drive conditions.

Nominal Speed: 30,000 rpm

The listed nominal speed provides a reference for evaluating operation under the manufacturer's nominal working conditions. Confirm the associated nominal current, voltage conditions, and thermal limits when selecting the motor for continuous operation.

Nominal Torque: 0.40 mNm

Nominal torque indicates the stated torque at the specified nominal operating point. It should be assessed alongside speed, current consumption, and temperature rise to determine whether the motor meets the application's motion requirements.

Stall Torque: 0.80 mNm

Stall torque refers to torque under a stalled-rotor condition as defined by the manufacturer's test method. A stalled motor may draw excessive current and generate heat; stall torque should not be treated as a continuous operating torque rating.

Torque Constant: 0.65 mNm/A

The torque constant describes the relationship between motor current and generated torque under the applicable operating conditions. Confirm the manufacturer's measurement method and current specifications before using this value for drive-system calculations.

5. Typical Applications

UAV and Miniature Aerial Equipment

The lightweight structure and high rotational speed may suit selected UAV subsystems and miniature mechanisms where compact drive components are needed. The appropriate application depends on the required torque, power, duty cycle, and environmental conditions.

Wearable Devices

The 5mm diameter and 2.6g weight make the motor a candidate for compact wearable products and miniature electromechanical functions. Product designers should verify operating noise, vibration, temperature, and power consumption against user and device requirements.

Robotics and Micro-Mechanisms

The motor can be evaluated for miniature robotic assemblies and compact mechanisms that require high-speed rotation within a restricted installation space.

Precision Instruments

Its small footprint may support integration into precision equipment and specialized instruments. Suitability should be validated through testing of speed stability, torque requirements, vibration, and control accuracy.

Intelligent Electronic Equipment

The motor may be considered for compact intelligent terminals and other electronic products that incorporate miniature moving components.

6. Product Selection and Integration Considerations

Before integrating the φ5mm Ultra-Micro Brushless Coreless Motor into a product, engineering teams should evaluate the following factors:

• Mechanical fit: Confirm the complete motor dimensions, mounting method, shaft geometry, and allowable installation tolerances.

• Electrical compatibility: Verify the 6V operating requirement, current consumption, driver compatibility, and electrical connection details.

• Load matching: Compare the required operating torque and speed with the listed nominal parameters.

• Thermal management: Assess temperature rise during the intended duty cycle, especially in enclosed miniature assemblies.

• Control requirements: Confirm the compatible brushless motor driver, commutation method, speed-control approach, and any feedback requirements.

• Operating environment: Check vibration, humidity, temperature, and other environmental conditions relevant to the end product.

• Validation testing: Test the motor under representative loads and operating cycles before moving to mass production.

These checks help determine whether the motor's compact dimensions and speed characteristics align with the final product design.
