Motors & Drives

This practical guide developed by Dave Polka, an industry veteran with more than 30 years of experience, is an invaluable resource for design engineers, automation and control specialists, maintenance technicians, and students. The basic theories of AC and DC drives haven’t changed but the technology certainly has, and this new edition takes a fresh look at how market demands have advanced motor and drive technology to lead the industry in new directions.

The second edition incorporates significant new material, including discussions on: - AC drives and machine safety
- Application-specific drives and soft-starters
- Enhanced programmability for AC drives including adaptive, function block, sequential, and IEC-61131-3 programming
- Master(leader)-follower, Ethernet, fiber-optic, and PLC communications
- The principles of DC and variable frequency AC drive technology
- An overview of drive components and types of drives, with special emphasis given to common applications and energy savings
- DC and AC motor and drive operation, as well as AC vector, servo, and permanent magnet motors
Inside you will also find easy to understand explanations, summaries, review questions, glossaries, reference tables for formulas and conversions. Great for a tutorial or desk reference!
