VFD stands for Variable Frequency Drive. They are used for controlling the speed of an AC motor. They are also used for ramping up a motor for a smooth startup, or to prevent a heavy load from straining the motor on startup. This is accomplished by adjusting the frequency delivered to the motor.
According to that nameplate, an 11A 3HP VFD will not work because your total for the machine is 12.3A, so that means getting a larger HP drive and de-rating it by 50-65%. It would likely cost you less to buy a 3HP VFD for the spindle and a smaller VFD for the feed motor separately. Jraef,

When I purchase my first BP, VFDs were outrageously priced and my experience with them (ABB drives) was that they could fail any time for mysterious reasons. So I found a 3/4 HP DC motor 90v with a 56C frame and installed that where the previous owner had installed a single phase motor. The power supply is 110 VAC and was @$60 …

vectorwarbirds. Some late input: my 70's era Bridgeport series 1 variable speed mill (2hp) has been running on a VFD for 10 years and its great. I do not change the setting from 60hz. I have 2hp rated VFD and use a 2second ramp for the motor. I never got the resistor pack for it so I can't use a faster ramp.

Two types of synchronous motor field exciter designs are suitable for starting and operating on a VFD: DC slip rings or an alternating-current (AC), brushless-type exciter. These designs can energize the field at standstill, during acceleration and while in operation.
the VFD can be operated to provide motor starting torque equal to approximately 80% of the motor's BDT. The combination of a VFD and motor can provide great advantage for starting a high inertia fan load, or to generate the high starting torque required in the starting of a kiln, a crusher or a loaded conveyor.
VFDs for such as your mill come in 115v and 220v single phase sources, your choice depending on your shop voltages. A second option is V/Hz or 'sensorless vector control'. V/Hz is the historical. older type which has no compensatory feedback to boost the motor power at low speeds.
Mill Speed is one variable that can often be easily changed with a variable frequency drive (VFD). The starting point for mill speed calculations is the critical speed. Critical speed (CS) is the speed at which the grinding …
Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials.

The VFD can only power the mill's spindle motor, and absolutely nothing else . A VFD is an electric motor speed/torque controller, not just some sort of power converter. Additionally, I took this opportunity to replace most of the mill's power related fuses with breakers. Fuses blow (figuratively and literally), and you often never have the ...
