AMP AC Square Motors - T-T ELECTRIC - #5

Text version of the page

5 Standards IEC600 34-1 Insulation Class H Temperature rise Class F Stator Fully square frame laminated, low loss, insulated on both faces. The laminations are welded together and the number of air channels through the iron core ensure a good heat transfer. Winding Conceived in order to withstand voltage peaks (du/dt) generated by the inverter. Thermal protection PTC 140°C thermistors (3 in series) in stator winding. PTC signal cable terminals are located into the terminal box. Rotor Consists of a core of laminations with the same magnetic properties as the stator laminations, and a squirrel cage made of die-cast aluminium or copper bars for larger frames. The skewed rotor core has an optimized number of slots and cooling channels for smooth running, high performance and good heat transfer. Vibration Class and balancing AMP motors are manufactured as standard to meet vibration class A and balanced with half key. Class B is available on request. Vibrations are expressed in mm/s, rms, using free suspension method and measured under no load.

Terminal box on the Right Hand Side (facing D-end). Cable outlet towards D-End. The fan blower is supplied without air filter as standard. Filter on request. Standard in IP54: Cooling by axial compact mounted 3-phase fan blower, induced draught, located at the back of the motor. Terminal box on top of the motor. Cable outlet towards D-End. Standard in IP55: Cooling by axial mounted 3-phase fan blower located at the back of the motor. Terminal box on top of the motor. Cable outlet towards D-End. Cooling by radial mounted fan blower is possible. Other cooling forms (in IC666, IC86W with exchanger) and positions for fan, terminal box and cable outlet are available on request.

Bearings Grease lubricated ball bearings are provided as standard for direct drive application. For pulley-belt drive, please contact our sales office. T-T recommend to use N-End insulated bearing or similar solution for output power above 100kW. Painting The standard AMP surface finish has excellent resistance properties. The painting system is suitable for humid environments. Standard colour of the motor is blue according to Munsell 8B 4.5/3.25 (similar to RAL5024). Paint thickness 60 microns.
