Demagnetization of Permanent Magnet Motors

MagNet's demagnetization analysis features allow the user to study the demagnetization characteristics of machines containing permanent magnets. It includes three probes of this phenomenon: the Demagnetization field, Demagnetization prediction field and Demagnetization proximity field. This example demonstrates how demagnetization properties are set in MagNet, and then apply this to a BLDC motor.

Demonstrating a variation of the MagLev suspension system

The performance of this machine is simulated using MagNet’s Transient 3d with Motion solver. The vehicle, consisting of the aluminum channel with payload, is given six degrees of freedom so that it is free to rotate about the roll, pitch and yaw axes and so that it is also free to move in all three dimensions (up-down, left-right, forward-backward). The vehicle is initially resting on supports 1 cm above the track, which is 0.5 cm below its equilibrium position when the track is energized.

Design and Analysis of a 2 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.

Designing a Servo Motor

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.
