The Efficiency of a Synchronous Motor and Mechanical Power Output

What is the efficiency of the synchronous motor and the mechanical power in HP that appears in the output of the motor?

The efficiency of a synchronous motor is a measure of how well the motor converts electrical energy into mechanical energy. It is calculated as the ratio of the mechanical power output of the motor to the electrical power input to the motor. In this case, the efficiency of the motor is 0.94, which means that 94% of the electrical power input to the motor is converted into mechanical power output. The remaining 6% of the electrical power input is lost as heat. The mechanical power output of the motor is 1.08 HP. This means that the motor can do the work equivalent to 1.08 horsepower. For example, the motor could be used to power a pump, a fan, or a conveyor belt.

Efficiency of a Synchronous Motor

The efficiency of the motor: 0.94 (or 94%)
Electrical power input: 380 V (rms) * 2.25 A = 855 W
Mechanical power output: 1.08 HP
Electrical power loss: 0.3 KW
Mechanical power losses: 0.1 KW
Core power losses: 0.2 KW The efficiency of a synchronous motor can be affected by a number of factors, including the load on the motor, the ambient temperature, and the quality of the electrical power supply. In general, the efficiency of a synchronous motor will increase as the load on the motor decreases. The efficiency of the motor will also decrease as the ambient temperature increases. The efficiency of a synchronous motor is an important factor to consider when choosing a motor for a particular application. A motor with high efficiency will consume less electrical power, which can save money on operating costs.
