The PK Series 0.72°stepping motor offers high torque, our lowest vibration and noise. This motor is wound in the bipolar New Pentagon configuration and therefore, require a New Pentagon bipolar type driver. The New Pentagon configuration ensures that maximum torque is being generated by the motor on every step. The New Pentagon configuration also provides extremely smooth motion as well as maintaining torque and step accuracy regardless of the step resolution. With the TH geared type, tapered gears are used for the spur gear's speed-reduction mechanism and the meshing gear. The tapered gear is produced through continuous profile shifting toward the shaft. The tapered gears are adjusted in the direction of the arrows, as shown in the figure, to reduce backlash. Available in 1.10 in. (28mm), 1.65 in. (42mm), 2.36 in. (60mm) and 3.54 in. (90mm) frame sizes. The PK Series stepping motor with encoder offers high torque and precise feedback capability. |
