Senior EM Design Engineer, High-Torque Motors (On-site)

raydar; Fremont (CA); On-site; USD 185,000 - 225,000; Full time

Job summary

Raydar is recruiting for a Motor Electromagnetic Design Engineer in Fremont, CA to own the electromagnetic side of motor development, from concept through prototype testing. You will partner with hardware teams to ensure your motors meet torque, speed, efficiency, and weight targets within packaging and electrical limits.

You should have hands-on experience with permanent magnet synchronous or brushless DC motors, and be proficient with electromagnetic FEM software.

Qualifications

• On-site in Fremont, CA.
• Experience with permanent magnet synchronous or BLDC motors.
• Proficiency with electromagnetic design software.
• Scripting in Python or MATLAB for parameter studies and tying simulations to tests.

Responsibilities

• Compare motor layouts and size core materials to meet torque, speed, efficiency and weight targets.
• Specify slot and pole counts, winding arrangements, magnets, laminations and air gaps, and assess saturation, losses, cogging and torque ripple.
• Build electromagnetic finite element models and analytical checks, recording assumptions and sensitivity to production variation.
• Align motor geometry with thermal and mechanical colleagues on heat flow, retention, clearances and manufacturability.
• Coordinate with drive and firmware engineers on motor parameters, voltage, current limits and operating ranges before design release.
• Support suppliers and prototype builds, and test motors on the bench or dynamometer to match measured results with predictions.
