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.<\/p>\n<h4>Wide Range of Output Torque and Sizes<\/h4>\n<p>The S-series slotless motors cover a wide range of torque and package sizes. Continuous torque ranges from 0.20 N\u00b7m to 29.09 N\u00b7m. Peak torque ranges from 0.82 N\u00b7m to 116.37 N\u00b7m. The open design of the S-series motors allows for custom winding or mechanical variations to meet any application need.<\/p>\n<p>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.<\/p>\n<h4>Easy Machine Integration<\/h4>\n<p>All S-series motors are supplied as two pieces \u2013 a slotless stator and a permanent magnet rotor. The stator is a standard 3-phase winding assembly with Hall-effect devices. They can be driven using a simple six-step or sinusoidal commutation algorithm. Aerotech\u2019s Ndrive 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.<\/p>\n<p>Custom variations can be engineered to your requirements with minimal lead time.<\/p>\n<p>Need help sizing your motor?
