ST SERIES MOTOR – DESCRIPTION
◆ General
ST series AC servo motors developed by Beijing KND CNC technique Co., LTD. are used for equipping
CNC machines. Foundation sizes contain 80, 90, 110, 130 and 150 five series, altogether more than 30 varieties.
Selection quality raw materials and parts can effectively keep motors working well during long-term,
high-speed, continuous running. The motor and KND SD series AC servo driver used together can make the
machine work in good performance.
◆ Characteristics of product
1. Full airproof and compact structure, beautiful contour.
2. Low harmonic, low magnetic resistance torque, high performance back electromotive force sine, sine-wave
current drive and excellent low speed performance.
3. Using high performance permanent magnet material and high grade cold rolled silicon-steel sheet, high power
and large overload ability.
4. Using optimization electromagnetism design, low noise, running steady, high efficiency, and keeping good
working condition during long-term continuous running.
5. Using optimization inertia design, quick motor response speed, suitable for various domains especially driving
CNC machine.
6. Using IP66 protection class to meet industry environment such as temperature -15℃ – 40℃, dust and oil
mist.
7. Using high-speed and high precision photoelectric encoder, working in with KND driving unit to achieve high
speed high precision and position control.
◆ Superiority of product
1. Standard equipping 2500 p/r incremental type encoder, and optional equipping absolute encoder containing
17-bit single-turn and 17-bit multi-turn encoder.
2. Work in with SD series servo driver and KND CNC system to make working more reliable and performance
more excellent.
