Calculation of numbers of consecutive starts
Calculation of numbers of consecutive starts
(OP)
Hi,
I would like to know how to calculate the numbers of consecutive starts of motor. Is there any publication telling about this ?
As I know, numbers of consecutive starts depends on mechanical drive moment of inertia. The more mechanical drive moment of inertia, the less numbers of consecutive starts of the motor.
Thank your,

For NEMA frame (small / medium) motors, the 1st linke provides a useful table.
For large motors, OEM info is essential as Ray said. The 2nd link provides only general discussion.

That may be a factor, but the limiting factor is the temperature inside the motor. Even with nothing connected to the motor, the number of starts is still limited.
