The motor is quiet thanks to the absence of friction — the only mechanical contact section is the linear guide. Coreless construction eliminates cogging. The motor is suitable for high-precision positioning applications that need a 0.09-nm resolution. Durable construction lets it serve such harsh conditions as vacuums or underwater. The motor's design eliminates backlash.
