■ Features For DC Brushless Motor
1.The characteristics of brushless motor
About brushless motors, there is no need to use mechanical contacts such as brushes and commutators, which are commonly considered drawbacks of DC motors. DC motors use brushes and commutators to rotate, thus requiring regular maintenance. In contrast, brushless motors utilize signals detected by Hall ICs and rotate by the ON/OFF of transistors in the drive circuit, eliminating the need for maintenance.
2.Stable speed control
Brushless motors continuously compare the set speed with the speed feedback signal from the motor to adjust the voltage applied to the motor. Therefore, even if the load condition changes, they can instantly adjust from low speed to the set speed and operate at this stable speed. Three-phase induction motors controlled by a frequency converter do not perform feedback control, so when the load increases, the speed will drop significantly. For applications that require high speed stability, it is recommended to use brushless motors.
3.Wide speed control range
Brushless motors have a wider speed control range compared to AC adjustable-speed motors and frequency converters. Since they do not have torque limitations at low speeds as seen with AC adjustable-speed motors, brushless motors are suitable for applications that require a certain amount of torque from low speeds to high speeds.
4.Saving energy
The rotor of the brushless motor utilizes permanent magnets, which can reduce secondary losses of the rotor. Therefore, compared to three-phase induction motors controlled by frequency conversion, brushless motors consume about 23% less power, contributing to energy savings in devices.
5.Low speed and high torque performance
DC brushless motor have a steady big torque when running at low speed.
6.Thin, high power
Brushless DC motors have a slim body and provide high power due to permanent magnets being used in the rotor. For example, the overall length is 75mm shorter and the output power is 1.3 times higher than that of three-phase induction motors with a frame size of 90mm. Using brushless DC motors can contribute to downsizing and space saving.
7.Protection function, help to protect the safety of the equipment system
Due to the load of the overcurrent, undervoltage, open phase protection, Our motor and driver can ensure the safety of equipment system.
