Built-in torque motors 1FW6

The built-in torque motor for applications with very high torques and high precision

Torque Motors 1FW6

Built-in torque motors are liquid-cooled resp. self-cooled high-pole permanent excited three-phase synchronous motors with hollow-shaft rotor. The motors are supplied as built-in components. For a complete drive unit, a bearing and an encoder system are required additionally.

1FW6 built-in torque motors for:

  • High dynamic response

  • High repeatability

  • No mechanical transmission elements such as couplings or gearboxes required
