ROTARY SERVO MOTOR SERIES


MOTX rotary server motors offer extremely high power density and energy efficiency due to their unique transverse flux motor design.

These motors can be connected directly to the mechanics that needs to be rotated.
This direct connection enables an excellent servo responsiveness that leads to a faster settling time for any motion and avoids gear losses.

RotRay motors are best suited for high performance and high precision applications in
Machine tools, Robotics, Automotive, Printing machines, Logistics, Power tools, and medical equipment.

Specification

  • Frame size: Ø22 to Ø263mm *can be scaled further
  • Peak Torque density: up to 9.3 Nm/kg / 32.2Nm/dm *For frame size Ø263mm
  • Rated Power density: up to 20 kW/kg *For frame size Ø22mm

Features

  • Scalable Performance (easily configurable dimensions, current, pole count and winding)
  • Lightweight and compact in size, yielding high torque and power
  • Slim design with high torque density allows volume-efficient scaling by stacking motors.
  • Direct connection to moving element, eliminating transmission losses and wear.

Advantages

  • UP TO 2X POWER DENSITY than available motors
  • HIGH ENERGY EFFICIENCY
  • COST EFFECTIVE MANUFACTURING & ASSEMBLY

Applications

  • High torque / high power
  • Volume / weight sensitive
