Ultrasonic motor, high frequency vibration motor, magnetic suspension motor, neodymium iron boron high-strength magnet, double ball bearing, is an ultrasonic motor that needs to be driven by high frequency, commonly used in electric toothbrush motors, there are A type: cylindrical motor, B Section: Flat motor. The pins of this batch of motors are two copper wires. The structure of the A-type motor is very close to the structure of the inner rotor brushle motor. For the technology we are amateurs, we do not know their working principle. The structure of the B-type motor is relatively close to other ultrasonic motors. Both models use NdFeB high-strength magnetic, double ball bearings. We don't know how to use ultrasonic motors. We only know that they need an external drive to work properly. Their drive boards are different from brushle motor drives and stepper motor drives. Buyers need understand how to use them. About shipping
