211-vacuum rated series motors are capable of up to 113mNm of holding torque depending, on stack size, and are said to be ideal for commercial grade vacuums
Servotechnic announces the release of the Lin Engineering 1.8 degree, Nema 11 vacuum motors.
The 211-vacuum rated series motors are capable of up to 113mNm of holding torque depending, on stack size, and are said to be ideal for commercial grade vacuums.
The Nema size 11, 1.8 degree motor measures a mere 28mm square and is available in three lengths.
It provides high torque in a small package.
The 211-13 produces 65mNm of holding torque; the 211-18 produces 97mNm of holding torque; and the 211-20 produces 117mNm of holding torque.
In order to make these small but powerful motors vacuum rated, Lin Engineering ensures that all of the special handling and parts necessary are used in the manufacturing process.
First of all, all paint and oils are removed from the motor.
Next, high temperature windings are utilised as well as Teflon leads.
Lastly, depending on the rating of the vacuum environment, either no-lube stainless steel bearings or special-lube stainless steel bearings are use.
During all of the manufacturing process, latex gloves are worn to ensure that no residue from human touch is left behind on the motors.
All of the above special parts and handling insure that limited outgassing and contamination will occur.
Applications include semiconductor, photonics, life sciences and specialist laboratory automation.
