Built-in synchronous motors 1FE1

The 1FE1 motors are built-in synchronous motors for high-performance motor spindles. Rotor and stator are ready for installation and have a cooling jacket for liquid cooling. The motors are suitable for the highest demands on machining quality, accuracy and smooth running. The spindle drive can be delivered in a high-torque or high-speed version.

1FE1 built-in synchronous motors - the motors for high speeds

• Compact construction through the elimination of mechanical components
• Short ramp-up and braking times
• High degree of shaft stiffness through large inner rotor hole
