Note:

Designation T – high-torque series

The length of electric motors with the designation T is indicated without Hall sensors

The inductance will be measured after fabrication

* Under development, specifications are planned

Application

  1. Small industrial robots and collaborative robots
  2. Pivoting devices
  3. Anthropomorphic and biomorphic robotic complexes
  4. Active exoskeletons
  5. Unmanned underwater vehicles
  6. Aviation
  7. CNC machines
Применение
  1. The best-in-class indicator of specific torque (rated and peak)
  2. The indicators of specific power and efficiency are at the level of the world`s best samples
  3. The ability to control the rotation speed in a wide range
  4. High positioning accuracy and no «bounce» when fixing the shaft positions
  5. The product is compact - wide possibilities for arrangement and design of robotic complexes
  6. It has successfully passed the test in space as part of the robotic complex «FEDOR» on the ISS
Применение

Особенности

  • The stator winding compound is resistant to thermal shocks from -60°C to +170°C (on request, electric motors may be manufactured for another version)
  • The design of the electric motor allows its installation in products for various purposes
  • Operation both under normal conditions and in aggressive environments (water, oil, acids)
  • Operation in radiation fields
  • The possibility of changing the method of connecting the windings
  • High peak torque rating
  • Frameless design and hollow rotor
