Inc. is seeking an experienced electrical engineer to join the Electrical Engineering R&D department, to develop advanced control electronics for electronically commutated 3 phase motors up to 15 KW. These motors are used for driving industrial fans and blowers in multiple market sectors. The US R&D departments are growing to become a local design center for the Americas. This candidate is a motivated EE department team member, interfacing with mechanical, motor, airflow and applications engineers locally, and in collaboration with engineering departments in the German divisions. The responsibilities involve multiple aspects of the design, including motor power electronics for up to 575 VAC, 3 phase power, power factor correction, winding drive circuits, EMC, serial and network communications, SMPS, microcontrollers, firmware, analog & digital interfaces and testing.
Essential Functions of the Job:
- Embedded controllers – Selection of microcontrollers suitable for the application. Functions for serial and network communications, internal status monitoring, failure logging and closed loop controls.
- Software development in C for embedded controls and PC software tools with Visual Studio. Microchip Technology processors and development tools are primarily used.
- Power circuit designs include IGBT bridge and driver circuits for voltages up to rectified 575 VAC 3 phase power with a clear understanding of the materials and spacing requirements of the circuit board. Knowledge of passive and active power factor correction methods and circuits is key for these products. A good understanding of power grid transients and anomalies is key in understanding how do design for robustness.
