Electric motors and generators
Our EM-PMI motors are available with power capacities up to 1,000 kW and can function as traction motors in heavy machinery, propulsion motors in marine applications, or variable-speed generators for hybrid vehicles or marine vessels.
Features and benefits
- Compact and robust structure
- High efficiency throughout the operation range
- Liquid cooling with water/glycol mixture
- Low coolant flow required; high allowed coolant temperature
- IP65 enclosure class to maximize reliability; IP67 enclosure class available in some machines
- Multiple mounting possibilities
- Capable of producing high starting torques (instant torque to non-moving wheel)
Applications
- Traction motors for off-road machines
- Propulsion motors and generators for marine vessels
- Variable-speed generators for hybrid vehicles and marine vessels
