Low Inertia Motors - Designed for general automation applications where high dynamic performance is required
HDM series of compact, high power density servomotors provides high dynamic performance with the advantage of small compact size and light weight. Designed for applications where space is at a premium and reduced motor weight is beneficial. HDM motors are available in 3 frame sizes with a stall torque range of 0.84 to 25 Nm.
HR series of low inertia motors provides high dynamic performance across a wide speed and torque range. HR/HRS motors are available in 5 frame sizes with a stall torque range of 0.6 to 67 Nm.
High Inertia Motors – for increased stability at low speeds
HJ series of AC servomotors have high inertia rotors along with larger than standard shafts and bearings to provide ultra smooth operation with minimal vibration and resonance when coupled to high inertial loads. Ideally suited for machine tool axis or for applications where the reflected inertia is high. HJ motors are available in 5 frame sizes with a stall torque range of 3 to 67 Nm.
Asynchronous Spindle Motors
ASM series of Asynchronous spindle motors have through lamination forced ventilation for high output power and compact size. Precision squirrel cage construction and finite balancing provides smooth operation and silent running for high end machine tool spindle applications or main-drive motors for all kinds of automated machinery.
