aerotech 1135 1

Two Powerful Aerotech 1135 DC Rotary Servo Motors w/Tach, Good Condition

* * NOTE * *: This item has a very low reserve price that I am sure will be met.

You are bidding on TWO used but in good condition servo motors by Aerotech. These motors were used on military aircraft, but were removed due to rigorous maintenance and replacement schedules. They cost the feds $3,000. The motors have tachs. Each weighs about 10.1 lbs.

See pictures below.

I have two more motors like that (1135), which I will put up for sale in a month or so.

They are guaranteed not to be DOA. Specifically, they were tested as follows: connecting 12V car battery to the power connectors made the motor turn nicely and quietly, albeit slowly (it has 80 V bus voltage). I have not, however, tested their tach/encoder features, due to lack of tools.

Satisfaction Guarantee: if you do not like these motors for any reason, you can return them back to me within four days of receipt. You will be responsible for all shipping costs as well as 10% restocking fee.

Nicks: one of the motors has a nick in the back, near the connector. It should not affect anything since that area of the motor is empty. See the sixth picture.

These are very nice motors, with double shielded bearings. From Aerotech website:

Brush, Rotary Servomotors

• Dynamically balanced, skewed rotor
for exceptionally smooth velocity

• Standard stainless-steel shaft resists
corrosion

• Double shielded bearing for long
motor life

• Options include tachometer,
encoders, metric flange, and
integral cable

The guys at Aerotech are fantastic. One of their engineers spent over half an hour with me, going over their models etc. That's even though I did not buy anything from them. So I hope that they will be able to resolve your questions, as well. For another motor (that I will keep for myself) they sent me a few missing machine screws, for free! They also sell a family of nice

controller cards and

amplifiers. The engineer that I talked to was able to send me the pinout information. Here it is. (some pins may be optional. Be very careful about connecting pins and double check everything with Aerotech)
