Brushless Motors

TG Series

The TG Series comprises high-performance, slotless, frameless brushless motor kits optimized for high power density, low weight and zero cogging. The motors feature an ironless, wave-wound stator and are available in sizes from 50 mm to 1 meter – with power ranges from milliwatts to megawatts. The TG Series is ideal for applications requiring particularly smooth, low-vibration motion. It offers high torque and high-speed capability, making it suitable, for example, for satellite reaction wheels, haptic feedback systems and starter-generator systems in aerospace applications. Available as a frameless kit or as a motor assembly with shaft and bearings, the series provides maximum flexibility for different integration requirements.

Key Features

  • Protection rating IP67: protected against fine dust and water ingress
  • Operating temperature, ambient: -40 °C to 125 °C
  • Bearings: special grease for a wide temperature range; Viton seals
  • Sealing: Viton seals
  • Stator: fully potted for optimum heat dissipation and maximum protection
  • Rotor magnets: potted and fully protected
  • Mounting screws: stainless steel
  • Ground connection, PE: threaded bolt for grounding and bonding 
  • Electromagnetic shielding: EMC-sealed; contact resistance < 10 mΩ
  • Drainage / pressure compensation: Gore-Tex protective valve, breathable vent membrane

Frameless Torque Motors

Compact high-torque solutions for seamless integration in harsh environments

Our frameless motors are designed to deliver exceptionally high torque and high efficiency in a compact, customizable design. Engineered for seamless integration into devices and systems, these motors enable precise motion control while offering the flexibility to meet individual application-specific requirements.

Key Features

  • High torque and power density in compact, lightweight or flat designs
  • Zero cogging and exceptionally smooth operation thanks to slotless or ironless stator technology
  • Available as axial-flux or radial-flux configurations for flexible integration
  • Scalable modular design – diameters from 30 mm to over 1 meter
  • Custom and modified solutions for application-specific requirements 

SA Series Frameless Axial Flux Motor

Our SA Series axial-flux motors are ideal for low-profile applications, such as moving camera systems, gimbals, scanning systems, imaging systems and image acquisition systems. The motors are slotless and therefore offer zero cogging torque. These axial-flux motors are designed for efficient manufacturing and are often the most cost-effective solution for direct-drive rotation. Thanks to their modular design, they can be easily scaled to large diameters with seamless transitions within the series. The motors can be realized in diameters from 30 mm to over 1 meter.
