more amps less torque??

If you reduce the start voltage to a motor, you will reduce the start current. (ohms law applies) If you reduce the start current, you will reduce the flux in the gap, (between rotor and stator) and therefore you will also reduce the starting torque.
The reduction in start torque is directly proportional to the reduction in voltage or current squared. i.e. half voltage will result in one quarter torque. One third current will result in one nineth torque.
Does this answer your question??
