The 5000 Series had Stepper Motor Drives rated in NEMA 23. They are highly efficient motors. They have high torque and inertia and are designed for speed and acceleration with a 2.5 A power level. They are equipped with a 35 Vdc with integral power supply. The 5000 series features improved torque linearity for high peak torque capability, an acceleration boost for intermittent duty applications, low detent torque harmonic, rugged “housingless” square frame, two phase design for driver compatibility, and smoother microstepping. These 5000 series motors come in a wide range of shaft and winding configurations for motor-application performance and options for mounting an encoder provision for optimum control scheme. They are ideal for applications that require demanding motion at moderate speed.
