Higher-phase Count Stepper Motors
Multi-phase stepper motors with many phases tend to have much lower levels of vibration, although the cost of manufacture is higher. These motors tend to be called 'hybrid' and have more expensive machined parts, but also higher quality bearings. Though they are more expensive, they do have a higher power density and with the appropriate drive electronics are actually better suited to the application, however price is always an important factor. Computer printers may use hybrid designs.

Famous quotes containing the words count and/or motors:
“This whole business of Trade gives me to pause and think, as it constitutes false relations between men; inasmuch as I am prone to count myself relieved of any responsibility to behave well and nobly to that person who I pay with money, whereas if I had not that commodity, I should be put on my good behavior in all companies, and man would be a benefactor to man, as being himself his only certificate that he had a right to those aids and services which each asked of the other.”
—Ralph Waldo Emerson (1803–1882)
“When General Motors has to go to the bathroom ten times a day, the whole country’s ready to let go. You heard of that market crash in ‘29? I predicted that.... I was nursing a director of General Motors. Kidney ailment, they said; nerves, I said. Then I asked myself, “What’s General Motors got to be nervous about?” “Overproduction,” I says. “Collapse.””
—John Michael Hayes (b. 1919)
