Robotics Motor Electromagnetic Design Engineer

Roboticsconnected; Fremont (CA); On-site; USD 110,000 - 180,000; Full time

Job summary

Dexmate is seeking a Motor Electromagnetic Design Engineer in Fremont, CA to develop PMSM and BLDC motors for integrated robot actuators. You will own the electromagnetic design from topology and sizing through prototype characterization, collaborating with mechanical, thermal and drive teams to meet packaging and duty-cycle constraints.

Responsibilities include evaluating motor topologies, designing windings and magnets, building FEA models, and coordinating with thermal and firmware engineers

Qualifications

• Hands-on electromagnetic design experience with PMSM or BLDC motors that were built and measured.
• Strong understanding of winding design, magnetic circuits, materials, loss mechanisms and torque production.

Responsibilities

• Evaluate motor topologies and size active materials for torque-speed performance and efficiency.
• Design slot/pole combinations, windings, magnets, laminations and air gaps; evaluate saturation, losses and cogging torque.
• Build electromagnetic FEA models and analytical checks; document material properties and tolerances.
• Co-design the motor with thermal and mechanical engineers for heat paths and manufacturability.
• Collaborate with drive/firmware teams on motor parameters, voltage, current limits and operating envelopes.
• Support suppliers and prototype builds; characterize motors on bench or dynamometer and compare with predictions.
