· Reasons to Determine Motor Loading Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor 's efficiency tends to decrease dramatically below about 50% load.

· An electric car motor works using a physical process developed at the end of the 19th century. This consists of using a current to create a magnetic field at the fixed part of the machine (the "stator") whose displacement sets a rotating part (the "rotor") in motion. We'll take a closer look at these two parts, and more, further down.

· Function of Fuse. In the field of electrical engineering, a fuse is a device that provides overcurrent protection to the functional electrical circuit. Here, we have listed a few major functions of the fuse. Acts as a barrier between the electric circuit and the human body; Prevents device failure due to faulty circuit operation
Also, we can entitle it as the construction of DC machine. A DC motor or machine consists of two windings namely field winding and armature winding. The field winding is stationary and the armature winding can rotate. The field winding produces a magnetic flux in the air gap between the armature and field windings and the armature is placed in ...
· The electric motor operation is based on the following points: • At least one of the two magnetic field is generated by a solenoid carrying a current. • Phase relation between the rotor and stator magnetic field (i.e. the load angle) must be always greater than 0° in order to keep the motor in motion (negative angles reverse the rotation).
Definite Purpose Motor: A definite purpose motor is any motor design, listed and offered in standard ratings with standard operating characteristics and mechanical construction, for use under service conditions other than usual or for use on particular type of application (NEMA). An example would a vertical holloshaft motor.
A contactor is a large relay, usually used to switch current to an electric motor or another high-power load.; Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts.If the series-connected heaters get too hot from excessive current, the normally-closed overload contact will open, de-energizing the contactor …
· Three-Phase Induction Motor: Being self-starting, the three-phase induction motors use no start winding, centrifugal switch, capacitor, or other starting device. Three-phase AC induction motors have various uses in commercial and industrial applications. The two types of three-phase induction motors are- squirrel cage and slip ring motors.
