High speed electric motor: High-Speed DC and AC Motor Solutions

When your equipment needs high rotational speed, fast response, compact size, or high power density, a high speed electric motor can give you a more suitable solution than a standard motor.

But high speed is not simply about increasing RPM. As motor speed increases, rotor balance, bearing performance, heat dissipation, vibration, noise, and motor control become more demanding. You therefore need a motor manufacturer that can control both the electrical and mechanical performance of the motor.

BG Motor provides high-speed DC and AC motor solutions, with customized designs for different equipment and operating conditions.

BG Motor High Speed Electric Motor Solutions

BG Motor offers several high-speed motor options, with brushless DC motors and AC motors as the main solutions.

The brushless DC motor range provides a particularly wide speed range, while AC motors are suitable when your equipment uses an AC power supply and requires high-speed operation.

These are BG Motor's stated customization ranges, while the final motor specification depends on your application, load, installation space, and operating conditions.

Voltage, Power and Current Need to Match Your Application

When you select a high-speed motor, voltage, power, and current should be considered together with speed and torque.

For example, if you require a 24V motor, the manufacturer still needs to know the required power, operating speed, load torque, and working cycle before determining the appropriate motor design. Current is also affected by the motor's efficiency, load, speed, and winding configuration, so there is no single current value for an entire motor series.

For this reason, providing voltage + power + speed + torque + working conditions gives the motor manufacturer a much better basis for developing the right solution.

High Speed Motor Specifications and Characteristics

A high-speed motor needs to maintain stable performance while rotating at a much higher speed than a conventional motor. The motor's rotor, bearing system, winding, cooling structure, shaft, and overall mechanical balance all need to be considered during development.

For your equipment, the most important specifications normally include speed, power, torque, voltage, motor size, shaft structure, noise, vibration, and cooling.

A high-speed motor with a very high maximum RPM is not necessarily the best motor for your equipment. If your machine requires high torque at a specific operating speed, the motor needs to be designed around that actual working point.

High Speed Electric Motor Applications

High-speed motors are used when fast rotation directly affects the performance, productivity, or response of your equipment. For applications such as winding, cutting, sewing, and alarm systems, the motor needs to maintain high rotational speed while also providing stable operation, suitable torque, and reliable service life.

BG Motor has been working with these types of applications for decades. As early as 1990, BG Motor focused on sewing machine motors and centrifuge motors as important product directions and began developing and manufacturing motors for these applications. This early experience gave BG Motor a practical understanding of the requirements of high-speed equipment, including stable rotation, compact motor structures, speed control, and continuous operation.

• Winding Machines

A winding machine often needs high-speed and stable rotation to improve production efficiency while maintaining consistent winding quality. The motor must respond quickly to changes in load and maintain stable speed during continuous operation.

For your winding equipment, BG Motor can develop the motor according to the required speed, torque, shaft structure, installation dimensions, and working cycle rather than simply providing a standard high-speed motor.

• Cutting Machines

Cutting machines require the motor to deliver fast and stable rotation to blades, cutting heads, or other rotating components. At the same time, the motor needs to maintain sufficient torque at the required operating speed.

In 2024, BG Motor provided a customized cutting machine motor solution for a Canadian customer. The project required BG Motor to consider the customer's actual equipment structure and operating requirements, demonstrating the company's ability to develop high-speed motor solutions for overseas industrial equipment manufacturers.

• Sewing Machines

Sewing machines have been one of BG Motor's long-term application areas. Since the early stage of its motor manufacturing development, BG Motor has focused on sewing machine motors and accumulated experience in high-speed rotation and stable operation.

For sewing equipment, simply increasing RPM is not enough. The motor also needs to provide fast response, appropriate torque, low vibration, and stable speed control because these factors directly influence the movement and consistency of the sewing mechanism.

• Alarm Sirens

In 2024, BG Motor developed and supplied a high-speed alarm siren motor exceeding 20,000 RPM for a customer in Turkey. This project demonstrates BG Motor's ability to develop motors for applications where very high rotational speed is a core requirement.

• Centrifuge Equipment

Centrifuge equipment is another important application in BG Motor's history. Since 1990, BG Motor has regarded centrifuge motors as one of its key development directions.

Centrifuge applications place strict requirements on rotational stability, vibration, speed, and mechanical reliability. Long-term experience in this area has helped BG Motor build practical knowledge for developing motors that operate reliably at high speed.

BG Motor High-Speed Motor Customization

A standard high-speed motor may not fit your equipment directly. Your machine may require a special shaft, smaller diameter, different lead-wire position, specific mounting holes, or a particular gearbox.

BG Motor can customize the motor according to your drawings and technical requirements.

The customization can include:

• Voltage and power
• Rated and maximum speed
• Shaft diameter and length
• Shaft shape and machining
• Motor diameter and length
• Mounting holes
• Lead-wire configuration
• Installation direction
• Protection level
• Insulation requirements
• Gearbox
• Brake
• Encoder
• Drive
• Connector

For customized brushless motors, BG Motor states that protection can reach IP68 depending on the design, and the motor can be integrated with gearboxes, brakes, encoders, and drives.

This means you can start from your equipment requirements rather than trying to find a standard motor that happens to fit your machine.

From Your Equipment Requirements to a High-Speed Motor

If you are developing a winding machine, cutting machine, sewing machine, alarm siren, vacuum cleaner, pump, fan, robot, or other high-speed equipment, you can provide BG Motor with the basic information about your application.

The most useful information includes the required voltage, power, operating RPM, torque, available installation space, shaft dimensions, working cycle, noise and vibration requirements, and operating environment.

If you already have a 2D drawing, 3D CAD file, motor sample, or equipment specification, you can send it directly to the engineering team.

BG Motor can then evaluate the application and develop the motor around your actual equipment requirements.
