MOTORS FOR HEAVY ELECTRICAL VEHICLES
8
2. Product description
The motor is an AC six (6) pole motor of synchronous type.
The motor features a tailored design, optimized for high energy efficiency and a competitive
performance/weight ratio.
The motor is actively cooled by a separate liquid cooling system which is connected to its integrated
cooling pipe via inlet and outlet connectors placed on the frame.
Special efforts have been made to decrease harmonic losses, noise and torque pulsations. The insulation
system contains corona resistant materials, has low water absorption properties and complies with
temperature class H.
Standard features (options are available)
• 3-phase permanent magnet synchronous motor
• Inverter adapted design of active material
• Class H insulation system
• Temperature sensors inside the stator winding
• Rotor balance grade G2.5 according to ISO 21940-11
• Operating ambient temperature between -20°C and +40°C
• Liquid cooled design
• Protection class for the motor, IP66
• Surface treatment, C3-M according to ISO12944-6
• RAL 9005
• Hazardous Voltage Interlock Loop (HVIL) function
