Design and Optimization of Electric Motors for the Automotive Industry

Engineering projects using the MotorSolve, MagNet and OptiNet software as part of the Automotive Partnership Canada (APC) project between McGill University, Infolytica Corporation, TM4 Inc. and Linamar Canada. Description of projects will include electric motor design, development of state-of-the-art optimization algorithms for multi-objective optimization and loss model development for accurate estimation of losses in electromagnetic devices. (This was originally presented at Engage 2015).

Design Optimization of an NDT Sensor Probe

Design of the probe and its suitability for detecting particular types of defects: starting from a model based on the WFNDEC Eddy Current Benchmark Problem 2, OptiNet was used to determine the optimal coil geometry and frequency at which the inspection should be performed.

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.

Designing Induction Motors

MotorSolve IM is a comprehensive tool within which modeling, design iteration and design validation can be carried out for induction machines. To facilitate this, user friendly and powerful modeling features as well as multiple types of analysis options of varying degrees of approximation and complexity have been implemented. These include equivalent circuit based analysis, AC analysis, PWM and dynamical motion simulations. Provided below is a summary of MotorSolve IMs’ modeling and analysis capabilities.

Detecting a Crack - A Problem in N.D.T. (T.E.A.M. Problem 8)

In this example, MagNet simulates an eddy current NDT problem: detecing the crack in a stainless steel block with a solenoid probe moving across its surface. The objective is to detect a crack by measuring the difference of magnetic fluxes through two solenoids.

Detecting Flaws and Nondestructive Evaluation (T.E.A.M. Problem 15)

This example demonstrates how MagNet can be used for non-destructive testing/evaluation and sensor problems. A circular coil moves along an aluminum plate that contains a slot. The goal of is to detect the slot by calculating the resistance and inductance of the driving coil at various positions.

Eddy Current NDT and Deep Flaws (T.E.A.M. Problem 27)

A coil is stationary over a sheet of aluminum that contains a screw hole. Inside of the screw hole, a flaw is to be detected by two Hall effect sensors. The sensors are used to measure the horizontal differential flux density .
