Voice coil linear motors, also known as Lorentz motors or scanner motors, are named for their structure resembling a loudspeaker's voice coil. They are fast-response direct-drive motors with zero hysteresis and zero cogging effects, featuring high frequency response, high acceleration, high speed, good force characteristics, easy control, small size, and small resolution. Abroad, voice coil motors are considered excellent servo drives. Depending on the configuration of the drive, feedback, controller, and control algorithm, voice coil motors typically achieve a motion frequency of 500-1000 Hz, and even higher.
Cylindrical solenoid motors, due to their ability to provide high thrust and speed, find extensive applications. These motors can generate a powerful force ranging from 0.7N to 2500N, accounting for 80% or even more of the market, with a stroke generally not exceeding 50mm.
Its basic working principle is that when an electric conductor passes through a magnetic field, it generates a force perpendicular to the magnetic field lines. The magnitude of this force depends on the length of the conductor passing through the field, the strength of the magnetic field, and the intensity of the current. The coil motor converts actual current into linear thrust or torque, with their magnitudes proportional to the actual current passing through. The thrust magnitude generated by the coil motor depends on the design structure and the intensity of the current: F = β*L*I. The relationship between current and the generated force is manifested as force sensitivity Kf in linear coil motors and torque sensitivity Kt in rotary coil motors. In our design, we define the unit of Kf as N/A and the unit of Kt as N·m/A.
