Induction motors 1PM4
Compact motor for high speeds with a hollow shaft and liquid cooling
The 1PM4 motors are induction motors with a hollow shaft. They satisfy the highest demands on maximum speed, smooth-running and vibration properties. The motors are prepared for the mounting of a rotary inlet for feeding liquids (cooling lubricants) through the rotating motor shaft for the internal tool cooling. The motors are optimized for applications with extreme ambient conditions (temperature, pollution, humidity) that do not permit air cooling.
