Direct Drive Motors
Industrial direct drive motors from global suppliers. Technical specifications, documentation, and RFQ capabilities.
Direct drive hollow shaft motors eliminate intermediate gearing to achieve exceptional positioning accuracy and repeatability at low speeds. The large through-bore allows cables, shafts, or optical systems to pass through the axis of rotation.
LVH Systems sources direct drive motors from Harmonic Drive LLC including KDU and HMA series. The KDU achieves 10 arc-sec positioning accuracy. HMA hollow shaft servo motors available in 5 frame sizes with 163 W to 1320 W rated output.
KDU Direct Drive Motor with Hollow Shaft
KDU series direct drive motors achieve 10 arc-sec positioning accuracy and plus minus 0.5 arc-sec repeatability with 0.16 arc-sec resolution. Large hollow shaft allows cables shafts or lasers to pass through the axis of rotation. Available in KDU-13SB with 7 Nm maximum torque and KDU-13WB with 15 Nm maximum torque. Incremental encoder 11840000 pulses per revolution. Combined with HA-770-2 AC servo driver.
HMA Hollow Shaft AC Servo Motor
HMA hollow shaft AC servo motors available in 5 frame sizes HMAC08 HMAB09 HMAB12 HMAB15 HMAA21A. Rated output 163 to 1320 W. Absolute encoder 17 bit single turn 16 bit multi turn. Available with or without brake. Connects with Mitsubishi MELSERVO-J4 Yaskawa Sigma-7 and Panasonic MINAS A5II drives.
