Electric motor + flywheel
Electric motor + flywheel
(OP)
Here is a couple of questions:
If a flywheel is attached to a 3/4 HP electrical motor will this increase the output of this set (motor+flywheel)?
If there is an increase than what is the maximum output that can be created in the case of a motor + flywheel using a 3/4 HP electric motor?
Regards,

RE: Electric motor + flywheel
Flywheel can increase the momentary overload torque which can sustained without going beyond breakdown torque. In some cases, this means you can comfortably power a larger load with the same motor.
When flywheel is added, effect on motor starting needs to be looked at.

RE: Electric motor + flywheel
The flywheel will store energy from the motor as it rotates the purpose of the flywheel is to smooth out fluctuations in torque loadings.
RE: Electric motor + flywheel
In other words, energy in = energy out. The flywheel adds no energy to the equation. It can store energy and release it later, but all of the energy it contains will have come from that 3/4 HP motor.

RE: Electric motor + flywheel
The high slip motors with flywheels are used on loads with short, high torque demands such as shears, punches and alligator shears.

Another application is to limit the rate of change - I have used flywheels on pump motors to reduce surge in the pipeline caused by starting and stopping pressure transients. (Soft start does not protect from power failure).
