[QUOTE="David (saltas), post: 2982825, member: 54587"] higher voltage gives more torque torque is proportional to voltage squared. Start up currents are six to ten times the rated full load current of the motor Single phase motors are not that efficient 65%ish three phase motors of the same horse power are better than 90% efficient and half the physical size. the high speed motor is two poles and gets two impulses each revolution the slower motor is four pole and gets four pulsed per revolution the three phase equivalents will be getting 6 and 12 pulses per revolution these little snipits don't answer your question but should help you later when you get stuck into sorting it out.
