What is 'locked rotor current'? A motor at rest acts as if its rotor is locked. The locked rotor current and the starting current of a motor are one and…

Motor rated current also known as full load amperes (FLA) of a motor is the maximum current the motor windings are designed to carry. Here is a simple motor rated…

The speed of an induction motor is always lesser than its synchronous speed. The difference between the actual speed and the synchronous speed of a motor is known as slip.…

Most of the time, the motor nameplates do not contain the number of poles data on them. The number of poles in a motor can be calculated from its synchronous…

The "synchronous speed" is the speed of the rotating magnetic field in an electric motor. Here is a simple synchronous speed calculator. Always remember that the synchronous speed and rated…

The full load torque of a motor is the maximum torque that the motor can deliver when it is fully loaded. Here is a simple motor torque calculator that can…

Motor FLC or full load current or full load amperes (FLA) of a motor is the maximum current the motor windings are designed to carry. Here is a simple motor…

Star-delta starters are widely used for starting three-phase induction motors. It can reduce current inrush to 1/3 of direct-on-line starting current. Here is an advanced Star-Delta starter design tool that…

The direct-on-line starter is the cheapest motor starting method. In this method, full voltage is applied to the motor terminals. Here a comprehensive DOL starter selection tool, which can help…
