Electric Motor and Alternator Design Software
PASSAGE® software is a proven predictor of flow performance in
alternators and electric motors. The flow characteristics of the fan
are established. Results are described in terms of velocity and
pressure distributions within the rotating blade passages, and blade
loading diagrams. The results from 3-D flow models of the cooling
fan are analyzed to determine the impact that blade geometry has on
the noise and flow capacity.
The flow and heat transfer characteristics of the motor or
alternator are established using a system flow and heat transfer
model of the assembly. The objectives are to understand the flow
and thermal interactions while operating and to define changes that
affect winding and diode temperatures. The design parameters
analyzed include fan capacity, velocity distribution at fan
discharge and around the windings, or diodes winding surface area,
inlet and exit locations, clearances and stator surface area and
mass. The combined performance of the cooling fan and the flow/heat
transfer management within the assembly are studied. Technalysis
also provides electromagnetic simulation capabilities for evaluating
pole shape effects on noise generation.
Technalysis furnishes design services to meet the objectives of your
next motor or alternator requirement by:
- Evaluating current cooling performance
- Establishing cooling flow modifications for performance
improvement:
- increased cooling capacity
- improved efficiency
- reduced fan noise
- better heat management
