Motor-CAD – Partner Software

The software Motor-CAD® is developed by Motor-Design Ltd. (UK) and represents a worldwide unrivalled product for the thermal analysis of electrical machines based on networks and analytical heat transfer equations.

Given the selection of a motor type, construction, cooling method and user inputs for geometry, material and losses, Motor-CAD® creates, parameterizes and solves thermal networks.

Due to the analytical approach and in contrary to the “Computational Fluid Dynamics” method, computational times of Motor-CAD® are very short. Therefore alternative designs may be compared and parameter variations can be investigated. Motor-CAD® calculates steady-state values and performs transient calculations as well as sensitivity analyses.

The following motor types are available:

brushless permanent magnet (BPM) motors,

outer rotor BPM motors,

induction motors,

permanent magnet dc machines,

switched reluctance motors,

synchronous machines,

claw pole machines,

single phase induction machines

Geometry editors support the input of stator, rotor, winding and bearing data. Material data as thermal conductivity, thermal capacity and density may be entered by the user or taken from a data base. Motor-CAD® provides models for the adaptation of loss values to temperature, speed and load. A powerful unit converter supports the input of values from different sources.

Models for the following cooling methods exist:

natural (TENV) and forced (TEFC) convection,

through ventilation,

water jackets (several configurations),

submersible,

wet rotor and wet stator,

spray cooling,

radiation,

conduction.

Results calculated by Motor-CAD® may be exported easily to Excel and Matlab. Motor-CAD® may import data from SPEED and perform iterative calculations together with SPEED.

The thermal networks generated by Motor-CAD® can be expanded by means of an integrated network editor. In order to integrate them into more complex system simulations, an import function to Portunus® is available. This import places the objects of the network automatically into the Portunus® schematic where additional components may be connected.

Motor-CAD® is ActiveX enabled, and can be easily controlled using Matlab®, Excel® and C++.

Motor-CAD® is used worldwide by many companies and universities. Customers range from multi-national household names to small companies with highly specific demands.
