The S-series motors are Aerotech’s high-performance brushless, frameless torque motors. The motors feature rare-earth magnets for maximum torque and acceleration in a compact assembly – while delivering excellent velocity stability.
•Frameless design for easy integration into OEM machines
•Various winding options available
•Includes Hall effect sensors for commutation
•CE approved, follows the EU 2015/863 RoHS 3 directive
The S-series motors utilize a slotless stator design and high pole-count rotor to provide zero cogging for exceptional velocity stability. The laminations contain no slots, eliminating torque ripple and cogging torque that produces velocity disturbance. The S-series motors are well-suited for direct-drive applications such as printing and scanning where velocity ripple cannot be tolerated.
Wide Range of Output Torque and Sizes
The S-series slotless motors cover a wide range of torque and package sizes. Continuous torque ranges from 0.20 N·m to 29.09 N·m. Peak torque ranges from 0.82 N·m to 116.37 N·m. The open design of the S-series motors allows for custom winding or mechanical variations to meet any application need.
The S-series motors are designed for applications in OEM machines. The S-50 (50 mm diameter) motor is ideal for small, tight spaces such as spindles or small feed rolls. The S-180 (180 mm diameter) and S-240 (240 mm diameter) can accelerate large print drums or precision positioning tables.
