Precision Positioning

Actuators

Actuators convert the rotary motion of an electric motor into linear motion. Types include rod and rodless, with either stepping or brushless servo motors.

Gearboxes

Gearboxes provide speed reduction, increase applied torque, and reduce the load inertia that is reflected back to the motor. Technologies include spur gear and planetary gear models, both in-line and right angle.

Linear Guides, Ball Screws and Monocarriers

Precision mechanical components that convert rotary to linear motion. Available in a wide range of sizes and used to provide and support linear motion in machines.

Precision Positioners

Linear tables designed to move and position loads, with either linear or rotary motion. Usually powered by a stepping or brushless servo motor which can be either rotary or linear. Available with sub-micron repeatability.

Stepper vs. Servo Motor

Rotary to Linear Conversion

Linear motion systems driven by rotating electric motors commonly employ one of three rotary-to-linear conversion systems: ballscrew, acme screw or belt drive.

Lead Screw

Screw-drive mechanisms, whether acme screw or ballscrew, provide high thrust (to thousands of pounds) but are often limited by critical speed, maximum recirculation speed of ball nut circuits, or sliding friction of acme nut systems.

Ball Screw

ball

The majority of linear motion applications convert motor torque to linear thrust using ballscrews due to their ability to convert more than 90% of the motor’s torque to thrust. As seen below, the ball nut uses one or more circuits of recirculating steel balls which roll between the nut and ball screw threads. Ballscrews provide an effective solution when the application requires:

  • High efficiency, low friction
  • High duty cycle (less than 50%)
  • Long life, low wear

Acme Screw

acme

The acme screw uses a plastic or bronze solid nut that slides along the threads of the screw, much like an ordinary nut and bolt. Since there are no rolling elements between the nut and lead screw, acme screws yield only 30-50% of the motors energy to driving the load. The remaining energy is lost to friction and dissipated as heat. This heat generation limits the duty cycle to less than 50%. A great benefit of the acme screw is its ability to hold a vertical load in a power-off situation. The acme screw is a good choice requiring:

  • Low speeds
  • Low duty cycles (50%)
  • The ability to hold position while motor is off
