Humidifiers are used to increase the humidity in a confined space. They can be used to humidify living rooms and ventilators can be used to treat dryness. A typical household humidifier consumes a power of 25Watts. The energy usage of humidifiers can be calculated below: Enter the wattage, hours of usage, and cost per kWh. … Read more
A typical household exhaust fan consumes 40 watts of power. The energy usage of an exhaust fan purely depends on how many hours they spin. The energy usage of exhaust fans can be calculated here. Enter the wattage, hours of usage, and cost per kWh. The energy usage calculator for fans gives you the total … Read more

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 the same. It is the starting current drawn by a motor when full nominal voltage is applied to its terminals. Here is a simple locked … Read more
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 current calculator. Motor data input Motor Type Three PhaseSingle Phase Enter the motor rated voltage V Enter the motor rated power HPkW Enter the motor … Read more
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. Here is a simple induction motor slip calculator. If you want to calculate the synchronous speed, you can use the synchronous speed calculator tool. Measured … Read more
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 speed and its rated frequency. Here is a simple synchronous number of poles calculator. Number of poles calculator in a motor Synchronous speed Rated frequency … Read more
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 speed are two different parameters. Motor synchronous speed calculator Number of poles Supply frequency hz Calculate Result Synchronous speed RPM How to use the synchronous … Read more
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 help you calculate the full load torque of a motor. Motor torque calculator Enter the motor rated power HPkW Enter the motor rated speed RPM … Read more
