Voice coil motor programmable mode, voice coil motor, is a device that converts electrical energy into mechanical energy, and linear and limited swing angle movement. It uses the interaction of the poles in a magnetic field generated by an eternal magnetic field or energized coil conductor to produce a regular motion. Because the voice coil motor is a non-commutated power unit, its positioning accuracy depends entirely on the feedback and control system, and voice coil motor itself has nothing to do. With proper positioning feedback and sensing device its positioning accuracy can be easily achieved 10NM, acceleration up to 300g (the actual acceleration depends on the load of goods Hugh working conditions).
Voice coil motor specifications, many styles, whether linear or swing type, their basic principles of the same. When a conductive conductor passes through a magnetic field, a force perpendicular to the magnetic field line is generated. The magnitude of this force depends on the length of the conductor passing through the field, the strength of the magnetic field and the current. The voice coil motor converts the actual current into linear thrust or torque, and their size is proportional to the amount of current actually passed.
¡ô precise power, position, acceleration, speed control
¡ô Direct-drive actuators therefore have high accuracy and repeatable positioning accuracy
¡ô Complete position measuring system with grating and optical reading head (no wear) with
¡ô large size linear guide, so have a long service life
¡ô with current indirect power detection (switch detection)
¡ô digital and analog input and output channels
¡ô Power mode, speed mode and position mode can be switched at any time during operation
¡ô very high acceleration and speed
Programmable features:
Actuators can be programmed completely to achieve power, speed, position control, and can operate in three modes:
Power mode: Power mode is open-loop control and does not use encoder feedback, the actual position is still read from the encoder but has no effect on the output
Speed mode: The speed mode allows the actuator's axis of motion to move at a given speed, acceleration, and force level. A typical "soft landing"
Position Mode: The position mode allows the actuator's movement axis to move to various positions according to the acceleration, velocity and force used in the stroke, and it can perform absolute, relative, and learning position movements
Applications: Switch Testing, Automotive Threaded Testing, Bore Measurement and Groove Measurement, Pick and Place Applications, Tapping, Screwdrivers, Packaging, Pharmaceutical and Bio Industries, Location Welding, Scanning.
Tongmao voice coil motors use a high-efficiency coreless linear motor as a drive unit. Our direct drive platform has a higher speed, higher acceleration and stable accuracy performance.
