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. The PS gear mechanism is comprised primarily of a sun gear, planetary gears and an internal tooth gear. The sun gear is installed on the central axis surrounded by planetary gears enclosed in an internal tooth gear centered on the central axis. The PS gear offers high permissible torque and low backlash [35 arc minutes (0.58°)]. Gear ratios of 5:1, 7.2:1, 10:1, 25:1, 36:1 and 50:1 are available. 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. |
