Torque Motors and Spindle Motors

Direct Drive Technology

Torque Motors are three phase, rare earth (Iron Neodymium Boron) permanent magnet units and reach the highest continuous and peak torque density available today.

Imagine a World where power, precision and simplicity merge into a single revolutionary motion solution: Torque Motors.

The revolutionary e-motor concept that eliminates gears and coupling, thanks to direct transmission, ensuring immediate response and unparalleled precision. Mechanical components, moving parts, friction, failures, noise, energy consumption are strongly reduced as well.

Torque motors excel in applications requiring fast and smooth movements, extremely accurate controls, representing the the future of electric motion industry.

Ready to discover how this cutting-edge technology brings performance, efficiency and reliability to new levels? 

Direct Drive Motors Technology

Torque Motors, also know as Direct Drive Motors, directly applies torque to the load, without coupling like gears, belts or chains. It provides to the most accurate, compact, efficient electric motion solution today available on the market.

Direct Drive Technology results in motion control solutions with 

  • high power, precision, efficiency
  • smooth, quiet and highly dynamic operations
  • compactness and easier design and installation 
  • low energy consumption and cooling demand
  • drastically reduced maintenance and failures
  • extended total lifetime, reducing the investment cost
  • high reliability and service time

Direct Drive Motors Performance

On the performance side, torque motors lead to high rigidity, low cogging and zero backslash systems, with high torque and high speed and precision capability.

Thanks to the absence of gearbox and transmission systems, direct drive motors present low torque to inertia ratio, so just a small torque is needed to provide fast movements and high accelerations and decelerations. System efficiency is heavly improved as well.

High Torque Motors

Direct Drive Motors are named “torque motors” as well, because they lead high torque values comparing to traditional electric servo motors.

Thanks to high specific torque density, frameless torque motors are very suitable for space saving solutions, ideal for small building volumes, as for high volume applications.

Direct Drive Motors offer to machine builders unparalleled possibilities for space optimization and better design of supports cooling system and joints.

Frameless Configuration

Direct Drive Motors are particulary advantageous in frameless configuration, as they eliminate frame, and housing.

Frameless design results in a more compact and lightweight motion solution, reducing noise, vibrations, maintenance, costs and overall complexity.

The absence of  an housing frame facilitates better integration, scalability, and easier installation and inspection.

As explained, frameless configuration does not require housing frame: the motor consists only of the rotor with permanent magnets and the stator with windings producing the electromagnetic field.

Windings can also be customized with customer preferences or specific design demands.
