As devices and equipment grow smaller and more portable, the components employed in their manufacture must also meet demands for lighter and more compact designs without sacrificing performance or life expectancy. This trend is seen across industry for a wide range of parts and products, including motors.
Micro motors are small, lightweight, and easy-to-use motors designed for low power consumption and minimal electromagnetic interference. These qualities, among others, make them well-suited for use in compact and complex spaces with restricted power budgets, such as advanced electrical and electronics systems.

Compared to traditional motors, they have a variety of benefits. In addition to their suitability for limited space environments, our micro motors offer:
- Quieter operation. They are designed to be quieter than other motors.
- Superior performance. Despite their compact size, they provide excellent energy efficiency, long-term reliability, and precise control, as well as give vibration-alerts to keep industry professionals apprised of the equipment status in real-time. Additionally, their low inertia and inductance winding enable highly dynamic performance, while their lower risk of cogging makes for more reliable and dependable performance.
- Broader power options. The low current consumption and starting voltage of our micro motors make them suitable for use in battery-operated devices.
What Are Micro Motors?
Micro motors are characterized by their compact size, which makes them particularly useful in devices, equipment, and systems with limited space. In addition to their smaller size, they are more lightweight and portable than their standard-sized counterparts without losing power or functionality. Typical applications include use in drilling, grinding, polishing, and other industrial operations.
Brushed vs. Brushless Micro Motors
Micro motors are available in two configurations: brushed and brushless. Both types offer their own unique advantages and limitations. For example:
- Brushed DC micro motors are typically inexpensive and simple to operate and can operate in extreme environments due to the non-use of electronics. Their disadvantage is that since they use brushes that are in contact with the commutator, this causes friction which can eventually lead to motor wear over time.
- Brushless DC motors use electronic commutation instead of brushes which reduces wear and improves long-term reliability. They are usually smaller and lighter than brush motors with the same power output. Their disadvantage of brushless motors is that they are more complex and require an electronic system to control motor operation.

Industrial Applications of Micro Motors
Due to their compact and lightweight design, micro motors play a critical role in advanced machines and systems used across a wide range of industries. In particular, they’ve become a mainstay component within the medical and aerospace industries.
Medical Industry Applications
In the medical industry, the use of micro motors has led to significant developments in cancer detection and treatment. They enable medical instrument manufacturers to produce small but powerful biopsy devices that can collect and analyze samples with minimal incision damage.
Aerospace Industry Applications
In the aerospace industry, all equipment is subject to exceptionally rigorous standards. In addition to being built to precise and tight tolerance dimensions, they must be lightweight, reliable, and capable of withstanding extreme conditions, such as temperatures ranging from -60º C to 150º C, high levels of noise and vibration, impacts, and electromagnetic interference. Micro motors meet these requirements, enabling them to be used in a variety of aircraft systems, including for the regulation of fuel in engines and the maintenance of airflow in atmospheric systems.
Brushless Commutation Technology
Traditional motors use brush-type technology that limits product life and long-term reliability.
By using Brushless Commutation Technology and axially-grooved bearings, Micro Motors are smaller and more energy efficient than traditional small motors. They have an extended operating life and can last up to ten times longer than their brush-type counterparts.
Vibration-Alert Notification
Micro Motors also include vibration notification functions that enable portable hand held devices to alert end users.
Micro Motors can be used in a variety of applications, including:
- Portable medical devices
- Portable computers and electronics
- LED lighting
- Smartbooks and tablets
- Portable hand tools
- Mobile phones
- Vibratory cooling modules
- Blue-tooth earphones
- Alert functions for portable electronics
- Touch panel vibratory feedback systems
- Portable razors and personal hygiene products
- Massaging goggles
- Wearable exercise and health monitoring devices
Micro Motors are better alternatives to traditional small motors for portable, handheld, and other electronic equipment that require energy efficiency, long-term reliability, and vibration-alert notification.
