Question

Applications:

Which motor would be best suited for the following applications

1.A lathe motor, requires constant speed when the cutting tool is applied to the work piece

2.An electric train, which requires large torque to accelerate a large inertia (lowspeed) but only a small torque once the load is moving (high speed).

3.A sheet metal punch press drive, requires a large drop in speed when punching action takes place (in order to provide its rotational kinetic energy to the load) but cannot speed up too much when the load is removed
