Characteristics and technical data
Applications
The1PH7 series is suitable for closed–loop speed control of main spindles on
machine tools, transfer lines and special purpose machines.
Characteristics
1PH7 motors are air–cooled four–pole squirrel–cage induction motors.
Depending on the shaft height, the 1PH7 series has rated outputs from
3.7 to100 kW at rated speeds from 500 to 2500 RPM.
