About the Role
You will design, simulate, tune, and validate motor control for permanent-magnet synchronous motors across robotic joints. You will develop control modes, calibrate sensors, characterize performance on dynamometers, define fault reactions, maintain control models, and work from simulation through full-robot validation.
Requirements
- Bachelor's degree in a relevant engineering field
- 3+ years of industry motor-control experience
- Production or formal-validation experience with field-oriented control for PMSM or BLDC motors
- PMSM dq-frame modelling and space-vector PWM knowledge
- Motor parameter identification and position-sensor calibration experience
- Dynamometer testing experience
- MATLAB/Simulink or Python modelling and simulation
- Embedded C/C++ reading ability
Responsibilities
- Design and tune field-oriented control and cascaded control loops
- Deliver torque and impedance control modes
- Build motor parameter identification processes
- Own encoder, Hall sensor, resolver, and commutation calibration procedures
- Reduce torque ripple and acoustic noise
- Implement field weakening, MTPA, and voltage-limit handling
- Define and validate fault detection and safe torque-off behavior
- Characterize motor control performance on dynamometers
- Build and maintain control-oriented plant models
