Study Notes

Motor Control Systems

  • Types of Motor Control:
    • Open-loop control: no feedback from the motor
    • Closed-loop control: feedback from the motor to adjust control
  • Motor Control Techniques:
    • PWM (Pulse Width Modulation): varies voltage to control motor speed
    • FOC (Field-Oriented Control): controls motor torque and flux
    • DTC (Direct Torque Control): directly controls motor torque and flux
  • Motor Control Applications:
    • Industrial automation
    • Robotics
    • Electric vehicles

Actuator Design

    • Electric motors (DC, AC, stepper)
    • Hydraulic actuators
    • Pneumatic actuators
  • Actuator Design Considerations:
    • Power density
    • Efficiency
    • Reliability
    • Cost
  • Actuator Selection Criteria:
    • Load requirements

    • Electrical (motors, generators)
    • Hydraulic (pumps, motors)
  • Power Transmission Components:
    • Gears and gearboxes
    • Bearings and seals
    • Clutches and brakes
  • Power Transmission Design Considerations:
    • Efficiency
    • Reliability
