• Stepper Motors (variable reluctance, permanent magnet, hybrid)
• Switched Reluctance Motors (construction, principle, drives)
• Permanent Magnet Brushless DC Motors (BLDC)
• Permanent Magnet Synchronous Motors (PMSM)
• Servo Motors (AC & DC)
• Linear Induction Motors

• Microstepping with current-controlled drivers to reduce resonance and increase position resolution.

1. Introduction to Special Electrical Machines: Overview of special electrical machines, their classification, and applications.
2. Brushless DC Motors: Design, operating principles, and control techniques for brushless DC motors.
3. Stepper Motors: Construction, operating principles, and applications of stepper motors.
4. Servo Motors: Design, control, and applications of servo motors.
5. Reluctance Motors: Principles of operation, design, and applications of reluctance motors.
6. Permanent Magnet Synchronous Motors: Design, operating principles, and applications of permanent magnet synchronous motors.

Design trade-offs (short)

• Simplicity vs. performance: SRM simple but needs complex drives; PMSM efficient but needs rare-earth magnets (cost/availability).
• Torque density vs. thermal limits: higher packing increases heat—requires cooling strategies.
• Cost vs. control complexity: sensorless and advanced control reduce sensors but increase algorithmic complexity.
