PM4 Powerful permanent-field synchronous motors

PM4 Powerful permanent-field synchronous motors

Having proven itself for years as a powerMELA® drive solution in mobile drive technology, Baumüller has now integrated its permanent magnet synchronous motor into its b maXX 5000 controller concept. The motor is available in the power classes of 40, 80, 140 and 200* kW and, in addition to the electromagnetic torque as a result of the Lorentz force, generates an additional reluctance torque. When used with the b maXX 5000, both torques — the electromagnetic and the reluctance torque — can be used, enabling optimized operation and high power density.

Characteristics:

• Permanent-field synchronous motor with deeply-buried magnets
• Optimized efficiency electric motor (up to 97%)
• Integrated or external electronic
• Robust construction (protection class up to IP6K9K)
• Direct conductor cooling with insulation oil for the 80 kW and 140 kW versions
• Water cooling for the 40 kW motor, oil cooling optional
• Cooling with industry standard solutions
• Field weakening up to 6000 rpm at constant power
• High coolant inlet temperature up to 65°C

Product advantage:

• Wide range of constant output due to use of field weakening
• Mechanical protection of the magnets
• Magnetic flux density
• High power density
• Direct conductor cooling
• Compact design

Customer benefit:

• Optimum adjustment to the load profile — high torque in the basic speed range and constant power at up to twice the basic speed
• Long running life through robust construction
• Excellent power output
• Low weight, small installation footprint, easier integration into existing vehicle designs and tight spaces
• Higher allowable coolant inlet temperature enables a smaller dimensioning of the heat exchanger
