SHA-SG Rotary Actuator

SHA Series AC Servo Actuators provide high torque and highly accurate rotary operation.
These hollow shaft servo actuators utilize Harmonic Drive® precision gears combined with a brushless servomotor and magnetic absolute encoder. The SHA Series is an advanced version of the FHA series AC Servo Actuators, featuring a larger hollow shaft with a smaller, outside diameter. The SHA Series is designed to operate with REL Seriesand HA-800 drivers.

Key Features:

High torque
Compact, slim design
Large center through hole
Low voltage winding available for SHA25A
New option - low voltage winding, 48V DC to 90V DC available for some sizes.
Connects directly with Mitsubishi Electric’s MELSERVO-J4 SSCNETⅢ/H, see brochure
Connects directly with Σ-7 servo drives from Yaskawa, see brochure
Also available to order as a “motor only”
