The ValueLine family of NEMA 23 servo motors is available in a 4-in. long version to complement the existing 2- and 3-in. versions. The 4-in. version produces more than 50 percent more torque than the 3-in. model. ValueLine servo motors are now available in 72, 132, and 200 W power levels, with rated speed to 3,000 rpm and maximum speed to 5,000 rpm. They offer extremely quiet operation and low speed smoothness, making them suitable for medical, laboratory, semiconductor, instrumentation, and light industrial applications. The ValueLine family produces constant torque across an entire range of speeds. The units feature rugged bearings for maximum reliability and accuracy, and can be used as cost-effective replacement for stepper motors where higher speeds and closed loop control are required.
