powerMELA®

Powerful permanent-field synchronous motors

Baumüller has integrated the permanent magnet synchronous motor, which has proven itself for years as the drive solution powerMELA® in the mobile drive technology, in its controller concept b maXX 5000. 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 deployed together with the b maXX 5000, both the the electromagnetic and reluctance torque torques can be used, thus enabling an optimized operation and higher power density.

Characteristics:

• Permanent-field synchronous motor with deeply-buried magnets
• Highly efficient motor (up to 97 %)
• Integrated or external electronic
• Robust construction (protection 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 standard industry solutions
• Field weakening up to 6000 min^-1 at constant output
• 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
• Compact design

Customer benefit:

• Optimal adjustment to the load profile: High torque in base speed range and constant output up to double the base speed range
• Long running life through robust construction
• Very high power output
• Lower weight and volume, easier to integrate in existing mobile concepts and small fitting conditions
• Higher allowable coolant inlet temperature enables a smaller dimensioning of the heat exchanger
