MotorSolve IM Thermal Analysis

In order to predict machine temperatures, the design of the electric machine needs to take thermal factors into account. In this example, a 4kW IM machine is chosen to demonstrate the new thermal analysis features within MotorSolve.

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

Wound Rotor Synchronous Machine for Traction Application

An example of an 8 pole 48 slot wound rotor motor is considered for traction based on the design of a similar interior permanent magnet (IPM) machine.

Design and Analysis of a 4 HP Wound Field Induction Motor

A 4 HP wound field induction motor example is used to demonstrate some of the design and analysis capabilities of MotorSolve IM. The motor contains 30 rotor slots and 36 stator slots. This example showcases the features of MotorSolve IM that allows the user to implement a typical design cycle. This includes automated winding selections, load point analysis, bridge simulations etc.

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.
