Working Principle

The MDM-21PH006B-K139 employs a brushless direct current motor, which consists of a stator, a rotor, a commutator, and control electronics. The stator is an electromagnet and the rotor consists of a rotor winding. When electric current is applied to the stator, it will generate a rotating magnetic field. This magnetic field will interact with the rotor winding, causing it to rotate. The commutator is used to switch the direction of the current in the rotor winding, thus allowing the motor to run in both clockwise and counterclockwise directions. The control electronics are used to control the speed of the motor by changing the frequency and voltage of the current supplied to the stator.

The rated voltage and current of the MDM-21PH006B-K139 are 6V and 4.6A respectively, and the standard rotation speed is 9500rpm. The device is designed to have a high level of efficiency with minimal power loss. At low loads, the motor is able to run at up to 9500rpm, while at high loads it can be adjusted down to as low as 500rpm. The motor also has a wide range of output torque, from 0.1Nm to 0.8Nm, which can be adjusted with the control electronics. The motor has a built-in over-current protection mechanism, ensuring that it does not overheat and damage itself or its surroundings.

In summary, the MDM-21PH006B-K139 is a high-performance brushless DC motor device, ideal for precision motion control. It has been widely used in industrial automation, medical devices, robotics, aerospace, home automation, consumer electronics, and educational robots. It has a rated voltage of 6V, rated current of 4.6A, standard rotation speed of 9500rpm, and a rated power of 34W. It has a wide range of output torque from 0.1Nm to 0.8Nm, and can be adjusted using the control electronics. Its built-in over-current protection mechanism ensures that it does not overheat and damage itself or its surroundings.
