The performance characteristics of the two-speed gearboxes for 1PH7 motors are as follows:

• Drive power up to 100 kW (134 HP)
• Constant power range at drive shaft up to 1:24
• Suitable for both directions of rotation
• Motor shaft heights SH 100 to SH 225
• Types of construction IM B35 and IM V15 (IM V35 available on request)

Mounting the change-speed gearbox outside the headstock of the machine tool has the following advantages:

• Easy adaptation to the machine tool
• Low noise and no temperature fluctuations due to gearing inside the headstock
• Separate lubrication systems for the main spindle (grease) and the change-speed gearbox (oil)
• Gearbox efficiency > 95 %
• Instead of V belts, the drive power can also be transmitted from the gear output by a gear wheel (available on request) or coaxially by means of a flexible coupling.
