I’m not sure where you’re getting your information, but good
topic. I needs to spend some time learning much more or
understanding more. Thanks for excellent information I was
looking for this info for my mission.

Linear Motors is an effective and user-friendly device that is used in a majority of fields to meet specific application requirements.

Comment on Choosing Between Servo and Stepper Motors by Sacha Marcroft

Good email but designed to create a bit of controversy. Closed loop stepper and position verification stepper are two different animals. In the olden days (old school) closed loop steppers were really just position verification systems. Move to a location and check to see where we are, if there is any error, make a correction. These days there are actual 50 pole (stepper motor) vector drives. Several drive and control companies have created drives that will actually drive a stepper motor as though it were a servo motor. Traditional servo motors have low inertia rotors with 6 to 8 poles which are designed for high acceleration applications or applications that require very high speeds 3500 to 5000 rpm’s. Steppers on the other hand have heavier, higher inertia rotors with 50 poles designed for high torque at low speeds. The heavier inertia rotors are also better for inertial mis-matches between rotor and system. So ultimately the 50 pole servo is ideal for slow speed, high torque applications for many of the reasons already discussed but regurgitated. 1) They are better for inertial mis-matches and may not require a gear box that are typically required for traditional servo motors, 2) they can be turned back into a steppers at zero speed. Meaning no dither or hunting 3) Stepper drives provide a fixed voltage and current that ultimately defines a torque curve. Once the torque at required speed is exceeded the motor stalls. Well as a vector drive, current is a variable so the motor has a little bit more available torque at certain speeds. Back emf is a given so for higher speed apps this is not a good animal. 3) However 80 percent of the automation apps require speeds of less than 20rps so for most applications speed is not the issue. 4) The holy grail of reasons is they are much cheaper… All servo means is that there is some level of feedback to which a control can make a desired error correction. So full circle which is better? The application should define the choice however with a little know how one can be a little more clever about the decision making process.

Thank you for your kind description and comparison.
The power parameter may weight a lot when speaking about robots. Isn’t it ? of course it is depended also on the accuracy and other relevant needed parameters.

Comment on New Planetary Gearbox Revolutionizes Deep Drill Technology by Electromate

Electromate — Thu, 02 Aug 2012 14:22:00 +0000

Yes, but the cost would be prohibitive as these specialty gearboxes sell for >$2500 US/ea.

Let me know if you are still interested.

Sir,

Thanks for your question. For long stroke lengths (over 60″) belt-driven actuators are preferred. For short stroke lengths, the choice between screw driven and belt-driven stages is application specific.
