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 40, 80 and 140 kW and generates reluctance torque in addition to the electromagnetic torque as a result of the Lorentz force. 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.
Technical data PM3
Subject to change
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
