Embedded Motor Control

PCB programmed by DMCDMC can help design your next motor control product. Our experience with all major motor types will help minimize development time and maximize efficiency. Motor control designs require extensive experience with control software, power electronics, thermal design and EMC/EMI for each type of motor.

DMC can provide the PCB design and software development for your motor control project. Our experts can help with selection of power electronics components to control the current and measure voltage feedback including Mosfets, IGBTs, and inductors.

DMC's Area of Expertise

  • Sensorless and Sensored Field Oriented Control (FOC) with Space Vector Modulation (SVM) to maximize system efficiency and ensure smooth operation.
    • Including sensorless zero and low speed rotor position detection
    • Traditional Sensor based FOC system utilizing incremental encoders, halls and/or resolvers for rotor position sensing
    • Advanced algorithms to decrease response times, increase DC Bus utilization and increase motor efficiency.
    • Current sensing techniques ranging from simple shunts to advanced in-phase sensors.
  • Permanent Magnet Synchronous Motors (PMSM) controlled by FOC and SVM
  • Brushless DC Motors (BLDC) to balance system complexity with motor efficiency controlled by Trapizoidal/Six-step control
    • We implement sensored and sensorless BLDC/trapezoidal control systems
  • Stepper motor controllers to guarantee accurate and reliable position control
    • Utilizing full or micro step techniques to optimize system performance and cost.
  • Brushed DC motors to minimize system cost
  • Induction motors controlled with vector control or linear/non-linear Volts/Hz control schemes.
