Stepper Motors

PRECIstep® stepper motors are two phase multi-polar motors with permanent magnets. The use of rare-earth magnets provides an exceptionally high power to volume ratio. Precise, open-loop, speed control can be achieved with the application of full step, half step, or microstepping electronics.

Two phase

The rotor consists of an injection moulded plastic support and magnets which are assembled in a 10 or 12 pole configuration depending on the motor type. The large magnet volume helps to achieve a very high torque density. The use of high power rare-earth magnets also enhances the available temperature range of the motors from extremely low temperatures up to 180 °C as a special confi guration. The stator consists of two discrete phase coils which are positioned on either side of the rotor. The inner and outer stator assemblies provide the necessary radial magnetic field.

Benefits

  • Extremely low rotor inertia
  • High power density
  • Long operational lifetimes
  • Wide operational temperature range
  • Ideally suited for micro-stepping applications

Two phase with Disc Magnet

The rotor consists of a thin magnetic disc. The low rotor inertia allows for highly dynamic acceleration. The rotor disc is precisely magnetized with 10 pole pairs which helps the motor achieve a very high angular accuracy.

The stator consists of four coils, two per phase, which are located on one side of the rotor disc and provide the axial magnetic field.

Special executions with additional rotating back-iron are available for exceptionally precise micro-stepping performance.

Benefits

  • Extremely low rotor inertia
  • High power density
  • Long operational lifetimes
  • Wide operational temperature range
  • Ideally suited for micro-stepping applications
