Electric Motor Handbook aims to give practical knowledge in a wide range of capacities such as plant design, equipment specification, commissioning, operation and maintenance. The book covers topics such as the modeling of steady-state motor performance; polyphase induction, synchronous, and a.c. commutator motors; ambient conditions, enclosures, cooling and loss dissipation; and electrical supply systems and motor drives. Also covered are topics such as variable-speed drives and motor control; materials and motor components; insulation types, systems, and techniques; and the installation, site testing, commissioning, and maintenance. The text is recommended for engineers who are in need of a convenient guide in the installation, usage, and maintenance of electric motors.Most common circuits automatically run equipment back if motorized, but on the first commission run it is prudent to take nothing for granted. ... 9.6.2 Diagnostica€” failure to run up: a.c. motors Event and possible causes (1) Motor crawls and is noisy: bearing stiction ...
