Product Name: Rotary Motors Frameless S

Product Description

• Slotless, brushless ring motors with high torque output and zero cogging

• Frameless design for easy integration into OEM machines

• Various winding and magnet options available

• Includes Hall board for six-step referencing of sine commutation

The S series motors are Aerotech’s high-performance brushless, frameless torque motors. The motors feature neodymium iron boron magnets for maximum torque and acceleration in a compact stator assembly.

High-Performance Design
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 that produces velocity disturbance. The eighteen high-energy magnet poles and slotless stator design provide superior smoothness and velocity control. 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) motors can accelerate large print drums or precision positioning tables. 
Easy Machine Integration
All S-series motors are supplied as two pieces – a slotless stator coil and permanent magnet rotor. The stator is a standard 3-phase coil assembly with Hall-effect devices. They can be driven using a simple six-step or sinusoidal commutation algorithm. Aerotech’s BA series amplifiers are performance-matched to the S-series motors for easy integration. The hollow rotor mounts directly to a drive axis with no gearing required. 

Custom variations can be engineered to your requirements with minimal lead time.
