Typical motor and belt efficiencies: * Motor 1kW - 0.4 * Motor 10 kW - 0.87 * Motor 100 kW - 0.92 * Belt 1 kW - 0.78 * Belt 10 kW - 0.88 * Belt 100 kW - 0.93

Depending on the motors input , we can measure the voltage consumed by a ceiling fan.

Normally , household fans consume 200 - 400 watts of energy.

hope this helps =)
