Product Announcement from H2W Technologies


3 Phase Brushless Linear Motor-Image

The 3 phase brushless (or AC servo) linear motor is ideal for long stroke, closed loop servo, linear motion applications. They can be used at speeds up to 240 in / sec [6 m / sec]. They are capable of very precise position, velocity and acceleration control when coupled with a linear encoder.

The 3-phase coil assembly can be commutated trapezoidally using integral Hall Effects or sinusoidally using software commutation in conjunction with the appropriate motion controller and sinusoidal amplifier.

The short encapsulated moving coil assembly moves thru a gap in the long "U" shaped magnet assembly. A customer supplied bearing system is required to guide the moving coil assembly and to maintain a .025" [0.63 mm] clearance between the magnet and the coil assembly.

The power to the motor (from a customer supplied PWM 3 phase brushless servo amplifier) is supplied to the moving secondary via a power cable.

Larger motors with higher forces are available, consult factory for details and drawings.

The motors are available in 3 different cross sections and 5 different coil assembly lengths.

Advantages:

  • Zero cogging
  • High speed and accelerations of light loads
  • Low moving mass
  • Uses standard 3 phase brushless amplifier
