Moving magnet actuator can replace pneumatic cylinders
System efficiency, size and operator comfort become more important every day. This means that equipment which has traditionally been fitted with a pneumatic system (including compressor, valves and bulky fittings) are being re-evaluated and re-designed. The MMB1555 moving magnet voice coil actuators from Magnetic Innovations have been designed to replace pneumatic cylinders in applications where speed, noise, system size and efficiency are key system parameters.
First voice coil actuator to include slide bearing system
The MMB1555 is the first in a range of low voltage (48V) single phase DC moving magnet voice coil actuators that includes its own slide bearing system. The MMB1555 two-wire stainless steel actuator only requires a single-phase DC current-source for operation, and with its compact size of 15 mm diameter by 55 mm in length it is able to deliver 2 N of continuous force and 6 N of peak force. The MMB1555 has an 18 mm stroke and a moving mass of 0.0179 kg which enables it to hit acceleration rates of 11 g continuous and up to 33 g peak. It is capable of handling several 100 millions of strokes without failures.
