I am recently retired and have been collecting various AC motors over the y ears with the thought that I would employ them for various jobs in my shop. I am setting up a wood lathe (Rockwell/Delta 14-11x48, model 46-111) and need a motor to power it. My two best candidates are as follows:
Motor 1- Craftsman ½ HP capacitor motor, 1750 rpm, 115V, 60 cy, 8.2A. It has a shaft out each end so rotation direction is not a problem.
Motor 2 – Craftsman 500/5000 rpm, 60 cy, 1 ph, 115V, 15A, ½ HP max. Duty cycle: Hi speed cont./ Lo speed intermittent. Speed control k now on opposite end of motor from shaft. Rotation direction is opposite fo r use on the lathe (without the motor sticking out and in the way) and I tr ied to switch wires to see if I could change direction, but NG.
I also have the following devices:
Variac Autotransformer W5MT, one side common line and load, 50-60 cy, line 120V, load 0-140V, 5A.
2000W AC50-220V SCR High Power Voltage Regulator Module, 25A max.
1. I know that there are various flavors of AC motors (capacitor start, un iversal, …). Can anyone explain the difference or point me to a go od web reference to understanding the differences of AC motors and how, if possible, to cjange their rotation direction?
2. The speeds on the lathe are controlled by stepped pulleys. I’ m thinking I might be able to also control speed by using the Variac or SCR . Would that damage the motor or even work in this case?
3. For the variable speed Craftsman motor, would there be a way to revers e the rotation? If so, and I ran it at say half speed, how would the term “intermittent” apply?
Looking forward to your wisdom, thanks,
