AC Synchronous Reluctance Machine for Traction Application
In this example, a 55 KW traction motor is designed using a stator that was originally designed for a squirrel cage induction motor for a similar output rating and application. The design of the new machine uses the stator of the induction machine and only the rotor geometrical parameters and configurations are used as free design parameters to achieve the target performance criterion.

Flux weakening of variable speed drives and comparison of CPSR in synchronous machines
Variable speed drives generally require electric machines to deliver constant power over a wide speed range and IPMs are known to have the best extended CPSR characteristics

Battery Charging with Maximal Peak Power Tracking
A maximal peak power tracking (MPPT) example for wind power plant is implemented in this example. The load is a battery that is subjected to a variable speed realistic wind profile. The system simulated consist of the following components; a wind turbine, a planetary gear system, a generator, a load (battery) and a 3-phase bridge regulator for the generator.

Field Oriented Control of an IPM
Field oriented control of an interior permanent magnet machine is presented in this example. A 70 KW IPM designed using MotorSolve BLDC is used as an example here; a summary of the motor characteristics, the PI control scheme, the integrated system that includes the motor model and SIMULINK interface and results of some test simulations for controlloing the speed of the motor.

Servo motor design using MotorSolve: Sizing
The sizing feature of MotorSolve can be used to obtain an initial design of a motor model at the onset on the motor design process. It is an automated feature which uses as input, the target performance specifications and design constraints of the motor, and outputs a complete design including model dimensions and winding details including winding layout, phase coil details and end turn electrical parameters.

Modeling and simulation of a Halbach cylinder BLDC Servo Motor
MagNet's magnetization pattern predicting capability is used to design a Halbach cylinder BLDC servo motor in this example. A four pole 12 slot, 3 phase machine is designed here including accurate modeling of an external, impulse magnetization of the Halbach cylinder.

Iron Loss Calculations in Laminated Structures
Most core loss calculation approaches apply Epstein frame data neglecting a number of significant factors such as drive types and differences between flux density. MagNet takes into account the histories of flux density in various parts of the machine, the drive type and separates the loss sources at the component level. Using the example of an interior permanent magnet motor, this novel approach is demonstrated.
