I recently purchased some additional CNC equipment and hence I am disposing of my surplus motors, etc. What is nice is that I have full sets of motors, for the most part, which means that you don't have to go searching for more of the same type. Everything is in good condition, unless otherwise noted. I am willing to send out photographs to anybody that has a serious interest. Just let me know what you want. Right now this is what I have for sale:
Ametek #79227 servo motors. I have two of these at $30 each, $50 for the pair. These are pretty good sized motors but they will require an external tachometer motor (I have some of these too) unless you are planning on just having an encoder feedback. They are single shaft units.
Electrocraft 0650 00 072 servo motors. I have five of these at $35 each, or $150 for the lot. These are a medium sized motor that should be excellent for a variety of machines. They have a 3/8" output shaft and are bout 6" long by 3" in diameter. The single shaft motors have an integral tachometer in them for feedback; they have a face mount or a side mount (the former being the method of choice for a CNC application, I suspect). All four brushes are accessible for maintenance.
QMC 23DCME1688 servo motors. I have three for these (actually, one is CMC ME2115-121D9) for $35 each, or $95 for the lot. These have integegral 512 CPR encoders (two are Lucas Ledex, the third by CMC. The output shafts are 1/4" and the motors are about 4" by 2" in diameter (excluding the encoder). The brushes are accessible for maintenance. One motor has a broken brush setup and the brush is missing. This will have to be resolved before the motor can be used. These are single shaft, no tachometer motors.
Electrocraft 0560 09 043 servo motors. I have four of these for $35 each, or $120 for the lot. These are nice units ideal for a smaller setup. The single shaft motors have integral tachometer coils and are about 5" by 2" in diameter. One of the motors has a piece of tape on it that says 'BAD', but there is a broken wire on the motor that, I believe, is the cause of this. The lead is still about 1/2" long, however, and when I hooked a battery up the motor seemed to work fine. The brushes are all available for easy maintenance.
Bodine Electric 201 3ML 2422 stepper motors. I have three for $85 each or $225 for the lot. These are all new, in the box and are 300 oz in motors for 3.1V and 4.0A. The motors are single shaft units with 8 leads and a ground wire. They are about 4" long and 3" or so in diameter.
I have several servo amplifiers that I will be doing something with in the near future.... When I know what I'm going to do with them I'll let the group know, assuming this sale here generates enough interest. The amps are all Advanced Motion Control amps of the smaller 6-12 amp variety.
All of the prices exclude shipping costs (I am in Sunnyvale, CA which is 94087). I will consider offers but would prefer to keep the items together in 3 or more unit lots. The reason for this is that I know how difficult it can be to find sets of motors for the projects we all like to work on!
Thanks,
Alan
