Design Verification by Simulation

The design of motors (or any other electromechanical system such as transformer, generator, alternator, magneto, sensors) are done using design rules which are essentially thumb rules based on approximations and hence they are conservative designs. The design of electric motors done using such thumb rules provide enormous scope for optimisation of performance characteristics.

Designs of electromechanical equipment can be verified in detail by using computer simulation techniques such as finite element method (FEM)/ finite element analysis (FEA). For example, all the losses such as iron loss, copper loss; magnetic flux and current density distribution, thermal gradients due to losses, demagnetization, leakage flux and inductance, vibration modes, stresses, noise (NVH) can all be simulated and verified without resorting to physical prototyping. ProSIM has the expertise and competence to conduct the design verification by simulation for all types of motors and electro-mechanical equipment. ProSIM uses high-end simulation software JMAG ( ) for the design verification and optimisation of all types motors and rotating electrical machinery/equipment. This includes
