1.The brushless motorized roller does not have an electromagnet in the center which can solve the heating issue effectively. 2.This brushless DC drum motor is suitable for low-speed transmission. 3.The conveyor motorized roller adjust the motor voltage by constantly comparing the set speed of motor with the feedback signal so that it can adjust low speed back to set speed instantaneously even if the load weight changes. 4.The rotor of this type of DC powered roller is permanent magnet. The power consumption can be reduced more than 20% compared with variable frequency controlled three-phases induction motor. This motorized roller is more energy efficient.
