Handbook of Electrical Motor Control for Integrated Systems: Variable Frequency Drives, Servo and Stepper Motion, PLC Networking, and Functional Safety

Electrical motor control sits at the intersection of more engineering disciplines than almost any other industrial subject: electromagnetics, power electronics, control theory, embedded firmware, industrial networking, electrical code compliance, and machinery functional safety all meet at the point where a motor actually turns a load.

An engineer or technician working on a real motor-control system has to move fluidly between all of these worlds: understanding why an induction motor slips, how a variable frequency drive generates its output waveform, how a servo loop is tuned for bandwidth and phase margin, how that control law becomes embedded firmware, how the system is wired into a PLC and an industrial network, how the branch circuit is protected under the applicable electrical code, and what functional-safety architecture the machine needs. Piecing this together from a shelf of narrow, single-topic books is slow, and the gaps between those books are exactly where costly mistakes happen.

This handbook was developed as a single, structured reference spanning that entire stack, from electromagnetic first principles through every major motor and drive technology, into the control loops, embedded firmware, PLC logic, and industrial networks that operate them, and finally into the protection, power-quality, and functional-safety requirements that make an installation compliant. Every stage includes fully worked, checked numerical examples rather than equations presented without application.

Benefits:

• Understand the electromagnetic and control-loop theory behind brushed DC, induction, synchronous, permanent-magnet, brushless DC, and stepper motors, with worked examples throughout.
• Select, size, and tune variable frequency and servo drives using the scalar and vector control mathematics used in industrial practice.
• Follow control theory into implementation, including embedded firmware, PLC motor-sequencing patterns, and industrial network timing.
• Apply branch-circuit protection, overload sizing, harmonic-distortion, and grounding requirements to real installations, with calculations shown in full.
• Work through functional-safety requirements, including performance-level and safety-integrity-level determination and the reliability arithmetic behind a redundant safety function.
• Commission and troubleshoot a system with a structured method, supported by a glossary, a units appendix, and drive-selection worksheets.

Key Topics:

Electromagnetic fundamentals; brushed DC, induction, synchronous, permanent-magnet, brushless DC, and stepper motors; power electronics and pulse-width modulation; scalar and vector variable-frequency-drive control; servo motion control and loop tuning; feedback sensors; embedded firmware; PLC programming; industrial networking; motor protection and power quality; and functional safety, commissioning, and troubleshooting.

This handbook is written for practicing electrical, controls, and mechatronics engineers who specify or support motor-driven equipment; industrial automation and drives specialists; senior maintenance technicians and electricians advancing into automation roles; engineering technology students and instructors; and safety and compliance engineers responsible for machinery functional safety. It assumes a working knowledge of basic circuit theory and is not an introductory book for a reader with no electrical background.

If the gaps between separate motor, drive, PLC, and safety references have cost you time or introduced risk into your work, this handbook was built to close them. Add it to your library and start working through the complete motor-control stack with the calculations shown at every step.
