Benefits of Moving Coil Technology

  • Lower moving mass with the voice coil actuator means extremely high acceleration and velocity, as opposed to the heavier “moving magnet” technology used in most linear motors.
  • Safe and energy efficient: operates at low current, typically at 1.5 amps at 24 volt DC.
  • Quiet (< 55dB), airless operation: no expensive compressed air generation required. No air consumption or air leaks to attend to. No compressed air generating environmental particulate contamination.
  • Long Cycle Life: >100 Million Cycles. 10x that of air cylinders or ball screw actuators.
  • Linear Rotary: SMAC invented linear rotary technology in 1998 and since have become the preferred solution for small parts assembly in the electronics industry, thread check in the automotive industry and capping in the packaging industry.
  • High Accuracy: Designed for precision movement applications. A very light moving mass results in high accelerations with no backlash.
 Programmable Features

SMAC actuators are totally programmable in force, acceleration and velocity. They give you the flexibility to run various products with a quick change over at the touch of a button. Multiple motion profiles (programs) can be stored/ preset in the SMAC controller. The actuator can operate in three different modes:

  • Force Mode: Force Mode is open loop, using no feedback from the encoder. The actual position is still monitored but has no effect on the output.
  • Velocity Mode: Velocity Mode allows the actuating rod to be moved with a given velocity, acceleration, force and direction. Typically used for a “Soft-Land” routine.
  • Position Mode: Position Mode will allow the actuating rod to be moved to various positions along the stroke using acceleration, velocity and force. It is possible to perform absolute, relative and “learned position” moves.

SMAC Moving Coil Actuators manufactures a wide range of precision programmable electric actuators based on its patented moving coil technology. These proprietary and patented moving coil linear motor based designs are technically far ahead of old generation pneumatic and electric actuators, including moving magnet linear motors. SMAC’s technological edge, combined with continuous cost down/quality-up process and its worldwide sales basis makes SMAC the most dynamic electric actuator manufacturer in automation today. Ideal for applications such as:

  • Luer capping
  • Vial capping
  • Press-on capping
  • Validation of prototype and production components
  • Small part assembly and verification
  • Inspection
  • Soft diversion and/or ejection of fragile containers
  • Handling of hazardous materials
  • And many more
