EM Motor Design Engineer job description

Raytheon Technologies is looking to hire a full time Electromagnetic (EM) Motor Design and Project Engineer within the Precision Mechanism and Controls department for their Missiles & Defense business located in Tucson, Arizona.  In this position, the candidate will be responsible for developing technical solutions and working with suppliers to develop high performance Brushed DC (BDC), Brushless DC (BLDC) and Permanent Magnet Synchronous Motors (PMSM) Experience is sought in electric motor developments for high performance actuation systems and motion control.

Prospective candidates must be able to design electromagnetics for permanent magnet BDC, BLDC, and PMSM motors as well as critically evaluate other motor supplier’s designs.  The candidate should additionally have a working knowledge of preferred motor design and construction details, but would not be expected to be the sole mechanical designer.  Prospective candidates will have technical ownership of all motor designs (including procured designs) and will be the technical expert on all motor related issues including recommending manufacturing and inspection work instructions and supporting failure investigations. 

The motor design engineer will be responsible for specification, design, development of fractional horsepower to several HP electric motors including, BLDC, PMSM, brushed motors; design and analysis of PM electric motors for low voltage, high voltage (270V dc), high altitude, and military temperature range environments. Design and analysis will include material selection, electromagnetics, electrical and thermal aspects. The position will work with mechanical engineering staff to perform mechanical design, analysis and drawings. Additionally, the position will be responsible for the project engineering of procured electric motors.

Day-to-day activities are highly collaborative, both internally across disciplines as well as externally with suppliers, partners and customers.  Hands-on opportunity is plentiful, as great emphasis is put on exposing designers to the hardware through participation in prototype building and verification testing, thus enabling firsthand knowledge of system performance. The position is expected to interact with a wide range of engineering and non-engineering disciplines in a matrix organization.
 

U.S. Citizenship status is required as this position needs an active U.S. Security Clearance as of day one of employment.
 
Required Experience, Skills & Education: 

• Eight 8 years of EM motor design experience (MS with 6 years or Ph.D. with 4 years of experience)
• Experience with electromagnetic, electrical and thermal design and analysis
• Experience designing and testing Brushed (BDC), Brushed Less (BLDC), and/or Permanent Magnet Synchronous Motors (PMSM)
• Bachelors degree in any of the following: Electrical, Mechanical, Aerospace, General, Systems Engineering, Math, Applied Physics or related field
• U.S. Citizenship is required

Desired Experience, Skills & Education: 

• Ten 10 years of Electromagnetic (EM) motor design experience including thermal effects
• Advanced degree in Mechanical Engineering, Aerospace Engineering, Systems Engineering, Electrical Engineering, Physics or Computer Science
• Understanding of common motor drive types (trap, sine, FOC SVPWM), but not necessary to be a power electronics engineer
• In-depth knowledge of 3-phase, trapezoidal and sinusoidal wound motors
• An understanding of feedback control systems and commutation techniques including Halls, Motor Positioning Sensors, Encoders and Resolvers
• Experience with dynamic phase advance / field weakening control techniques.
• An understanding of all types of losses in a motor including those related to PWM frequency
• Experience with magnetic saturation and the impact on motor performance over temperature
• Experience designing and/or analyzing brushed motor designs and mechanical commutation
• Familiar with motor kinematics
• Experience using motor design tools such as SPEED software
• Experience in motor mechanical packaging design
• Experience in the assembly and testing of motors
• An understanding of motor manufacturing methods
• Experience with the motor components supply base
• Project management of engineering projects
• Proven ability to deconstruct higher level tasks into discrete lower-level work packages and tasks
• Ability to estimate project / tasks level of effort
• Ability to articulate, in both oral and written form, to technical, non-technical and management audiences
• Proficient in Microsoft Office products (Word, Excel, Powerpoint)
• A working knowledge of Military and Industrial standards as they pertain to motors.
• Current DoD Security Clearance
