The performance features of the two-speed gearbox for SIMOTICS M-1PH8 asynchronous 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)

The advantages listed below are gained by mounting the gearbox outside the spindle box:

• 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)
• Gear efficiency > 95 %
• The drive power can also be transferred from the gearbox output via a gear wheel (on request) or coaxially via a flexible coupling rather than by a V-belt.
