In buildings, nearly three quarters of the electricity consumed is used to turn motors. For a typical motor, the lifetime energy bill is equivalent to 100 times the cost of the motor itself. The money invested in motors, is merely 1% of their total cost. And installing and maintaining those motors accounts for only 2% of overall motor costs. 97% of costs associated with motors are spent on the energy required to operate them. This course will provide an overview of power drive systems and motors along with insight on efficiency. This course will also cover, gears – types, efficiency and maintenance.
