Electrical Pumps, Motors, and MCC

In today’s modern plant, majority of rotating equipment are driven by electric motors. This course explains the construction and operation of squirrel-cage induction motors, synchronous motors and DC motors. Participants will learn basic maintenance and troubleshooting of squirrel-cage induction motors. Electric pumps are very common in the oil and gas industry. The course will cover types of pumps available and the criteria used in the selection of electric motors to drive them. Basic motor control circuit and typical motor protection schemes are covered for both low voltage and medium voltage motors. The course also includes construction and special features found in a typical low voltage and medium voltage motor control centres.
