- Fremont
Design and develop PMSM and BLDC motors for integrated robot actuators, owning electromagnetic design from topology to prototype characterization.
Responsibilities
- Evaluate motor topologies and size active materials for required torque-speed performance, efficiency and mass, including frameless or outrunner configurations where appropriate.
- Design slot and pole combinations, winding layouts, magnets, laminations and air gaps; evaluate saturation, losses, cogging torque and torque ripple.
- Build electromagnetic FEA models and analytical checks; document assumptions, material properties and sensitivity to manufacturing tolerances.
- Co-design the motor with thermal and mechanical engineers, accounting for heat paths, retention, clearances, assembly and manufacturability.
- Work with drive and firmware engineers on motor parameters, bus voltage, current limits, back-EMF and operating envelopes before design release.
Requirements
- Nice to have: frameless motors
- Nice to have: outrunner motors
- Nice to have: high torque-density motors
- Nice to have: low-cogging motors
- Nice to have: robotics
