RAS Series Hollow Shaft

Available now!

Description

DTI’s RAS Series rotary piezo motor represents a quantum leap in design of ultra-small size high-performance DC motors. Injection-molded using extremely durable, but light weight engineered reinforced thermoplastics, the RAS Series provides low cost with superior precision and ultrafast response/start-stop characteristics. Highly energy efficient, the RAS Series consumes zero power in hold position while still providing adequate torque. Available in a variety of configurations (including non-magnetic) the RAS Series is the ideal choice for high volume demanding OEM applications where superior performance and economical unit cost are important factors.
