Motor-cad is an advanced professional MOTOR design software that can analyze complex 3D temperature fields. Motor-cad is fast, accurate and widely used in measurement and fluid mechanics calculations. It is suitable for the analysis of brushless permanent magnet, induction and switched reluctance motor.

 

The thermal models developed are based on lump-line analysis provided near real-time computational speeds. The characteristics, precision, and mathematical method of each type of motor are given, including spontaneous convection, cooling, radiation, and conduction. A large database is defined for all internal and external structures of various motors to provide accurate models.

 

When entering arc or axial cross section data, motor-cad will provide a clear visual interface, allowing users to easily find errors and deficiencies. The user can choose whether flange, footer, or encoder are required. Can also choose to increase the ventilation duct, wind shield, axial or radial cooling rib to improve the cooling conditions of the motor. Motor-cad automatically divides windings into layers to calculate different temperatures in and out of the windings. The layer division is related to winding type, slot area, slot full rate, conductor number and selected wire gauge. It is mainly divided into two layer winding and single layer winding.

 

 

Motor-cad provides output interface with charting function for steady-state calculation data. Provide color legend corresponding to cross section. It provides an efficient way to check data, including parameters such as temperature, loss, and temperature rise. In addition, users can use the data editor to view the results in a table. After the transient calculation of motor temperature is completed, it can be output in the form of legend or data table. But the most important thing is that motor-cad can conduct transient analysis of temperature field of MOTOR under the condition of periodic load controlled by driving.
