The WebA 10 HP 6 pole motor is allowed 14.2 starts per hour with a 41 seconds off time before the next start. That’s more than twice the number of starts and less than half the off time when going from a 2 pole to a 6 pole motor. For a larger 250 HP 2 pole motor you are only allowed 1.8 starts per hour with a 1000 seconds off time.
