It is the main source of the low power factor in the motor. Disadvantages of Electric Motor The disadvantages of these motors include the following. In 2001 this motor was tested to 1600 hp with a sinusoidal constant frequency supply. Energy efficient motors are only marketed with NEMA B speed-torque characteristics. Energy efficient motors utilize high quality materials and employ optimized design to achieve higher efficiencies.

03 Source: NEMA Publication MG-1. Air gap The air gap is the space among the stator and the rotor. The capacity is up to 30,000 hrs but it needs little maintenance• An example of brushless design iswhich are primarily used in open-loop position control, with uses from printers through to industrial applications such as high-speed pick and place equipment.

The disadvantages of the electric motor are• An electric motor can be defined as; it is one used to convert the energy from electrical and mechanical. Usually, these are enclosed approximately a stretchy iron magnetic core to make magnetic poles energized through the current.

Energy Efficient Motors

Other parts of a motor are the frame, end bells, bearings, and a fan connected to the motor shaft. Thinner and higher quality steel laminations in the rotor and stator core allow the energy efficient motor to operate with substantially lower magnetization losses. Table 1 compares the current Standard full load nominal efficiencies for standard and energy efficient motors of various sizes.
