AC Square AMP Seriesby T-T ElectricAMP series, square frame AC motors are fully laminated, 4 pole, square frame. Output: 1-1000 kW (1400 HP) Torque: 110-6400 Nm The AMP series 112-355 motor range comprises of: Frame SizeCore Lengths 112 A,B,C 132 A,B,C 160 A,B,C 180 A,B,C 225 A,B,C 280 A,B,C 355 A,B,C Type designation example - AMP 180-4 B AMP = Type of motor 180 = Frame size 4 = Number of poles B = Core length The mechanical and technical characteristics of AMP motors can be compared to DC motors. Standard Features Conforms to IEC600 34-1 Class H Insulation Class F Temperature Rise 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 The winding has been manufactured to withstand voltage peaks (du/dt) generated by the inverter Thermal protection - PTC 140°C thermisstors (3 in series) in stator winding. PTC signal cable terminals are located into the terminal box The 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. AMP motors are manufactured as standard to meet vibration class A and balanced with half key. Class B is available on request Cooling and terminal box position - in IP23: cooling by radial mounted 3-phase fan blower located on top at N-End of the motor. 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. 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. 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 upon request Mounting forms - Standard IP23 in 112-355: IM1001/B3 and Standard IP54/55 in 112-160: IM2001/B35 and in 180-355: IM1001/B3 Grease lubricated ball bearings are provided as standard for direct drive application. For pulley-belt drive, please contact us to discuss. It is recommeded to use N-End insulated bearing or similar solution for output power above 100kW 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
