Overview: Brushless DC Motors

A BLDC (Brushless DC) motor is a highly efficient, electronically controlled electric motor that eliminates physical mechanical brushes. Instead of relying on parts that wear out over time, it uses an electronic controller to switch the current, offering longer lifespans, greater reliability, and quiet operation.

Product advantages

Higher Power Density

BLDC motors deliver more output power within a smaller frame compared to induction motors. Their permanent magnet rotor design enables compact, lightweight solutions without compromising torque or speed.

Higher Efficiency

By eliminating rotor copper loss and reducing heat generation, BLDC motors achieve significantly higher efficiency. This lowers energy consumption, reduces operating costs, and extends battery life in portable applications.

Precise Speed and Torque Control

Electronic commutation allows accurate control of speed and torque. This ensures smooth operation, fast dynamic response, and superior performance in applications requiring precision, such as robotics and medical devices.

Long Service Life & Low Maintenance

Without brushes or commutators, BLDC motors avoid mechanical wear, minimizing maintenance needs and ensuring long-term reliability even in demanding environments.

Wide Application Flexibility

BLDC motors are available in a broad range of diameters and power ratings (Φ22 mm to Φ110 mm, 5 W to 1200 W). This allows seamless adaptation to diverse industries—from small household appliances to industrial automation.

Low Noise & High Reliability

The brushless design reduces electrical and mechanical noise, improving user comfort and ensuring stable performance in sensitive equipment. This makes BLDC motors ideal for quiet, high-reliability applications.

Structure

Our offers brushless motors with four different design principles.The two- and four-pole BLDC motors have an elongated cylindrical shape. Similar to the DC-motors, the winding is on the outside and the magnets on the inside, except that they perform the "reverse" function in the brushless variant: Winding = Stator, magnets = Rotor.

In the two-pole motor, the rotor consists of a single magnet with a north and a south pole. In the four-pole motor, the rotor has two alternating north and south poles.

In a third version, the brushless motors of the B-Flat series feature a flat multi-pole design. In this model, three self-supporting windings are mounted on a circular stator disc. The rotor consists of a magnetic disc that is also circular. This unique layout enables an extremely flat design.

FAQ

Q: Are brushless motors waterproof?

A: Brushless motors may be water resistant, but are not inherently waterproof. Tiny water particles can seep into the bearings and wear them away.

Q: Are brushless motors more efficient than brushed motors?

A: Brushless motor efficiency is much higher than that of brushed motors. Brushless motors are 85-90% efficient while brushed motors are 75-80% efficient.

Q: Are brushless motors faster than brushed motors?

A: Yes, brushless motors are faster due to the lack of friction between their moving parts and higher efficiency, which allows them to convert more energy into mechanical power.

Q: Are brushless motors quieter than brushed motors?

A: Yes, brushless motors generate less noise than do brushed motors because they do not contain brushes. Since there are no brushes, there is less noise created by movement.

Q: What is stall torque?

A: Stall torque is the torque at which the shaft ceases to move.

Q: What is rated torque?

A: Rated torque is the torque at which the motor can operate continuously at a safe level.

Q: What is peak torque?

A: Peak torque is the torque at which the motor can operate for a brief period of time. Motors will be damaged if run at peak torque for long periods of time.

Q: Can I run a brushless DC motor off of a battery?

A: Yes, along with a Brushless DC Controller.

Q: Can I run a brushless DC motor off of 110 VAC?

A: Yes, along with a brushless DC controller.

Q: Will a brushless DC motor slow down when the load is increased?

A: In closed-loop control, the brushless DC motor will not slow down as long as the torque of the motor is strong enough. However, it will always slow down with open-loop control.

Q: Is it possible to burn a brushless DC motor by applying too much load?

A: Yes, it is possible to burn the motor by apply too great a load, but it is protected if the controller has a current limit provision.

Q: Does sell encoders for BLDC motors?

A: Yes. We supply encoders of any order size to customers who require a complete motor/encoder assembly ready to mount. We can assemble the encoder to the motor for a nominal charge.

Q: What is the life expectancy of Motors?

A: BLDC motors have a 20,000-hour life expectancy under normal operating conditions. warranty is 12 months after the invoice date.

Q: Can a disassembled BLDC motor be cause for damage?

A: Yes, disassembling the motor can lead to further damage and malfunction. If you have a motor failure or are concerned about the performance, contact wer . Please note that the warranty period is 12 months from the date of invoice.

Q: What should I do if my motor stalls at high speed when the temperature exceeds 65° C?

A: Try to keep the BLDC motor below 60° C or move up one stack length in your motor.
