Stators
Stators are available with single-phase or poly-phase windings. Slot insulation and winding impregnation comply with class F of VDE 0530 Regulations. Maximum permissible sustained temperature is 155°C. The flexible leads are generally designed with Teflon insulations and are oil resistant. For temperature monitoring, thermal switches (PTC or KTY resistors) can be fitted into the stator. Dimensions are specified in the standard program. Windings are supplied in accordance with customer specifications. All stators have to pass a 100% test with impulse voltage and a high voltage test.

Rotors
The cage consists of specially selected high-pressure diecasting. This insures almost 100% filling of the slot cavity, so that greater mechanical strength of the rotor is achieved and the out of balance centrifugal forces are low. This inherent balance remains constant.
Special modifications can be made to reach higher speed, for example armouring or closed groove.

Special designs on request
• Potted winding heads (e.g. for vacuum or laser applications)
• Stators potted in SycoTec manufactured or customer supplied enclosure
• Mechanical finishing of stators and rotors
• Rotors assembled with shafts (shaft manufactured based on customer specific drawing)
• Rotors with reinforcement rings/armouring (for high speed applications)
• Copper stuck rotors
• Diecasted copper rotors
• and so on

The following pages will show you some power calculation examples for 2-, 4- and 6-pole three-phase induction motors . The calculation examples should help you to define your own drive design in regards to mechanical dimensions and power values. The calculated motors are not our standard program range and they are not available to be delivered ex stock!

Further sizes available on request (up to max. diameter 300 mm of the stator).
