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 PN gear employs a planetary gear speed-reduction mechanism. The PN gear achieves the specified backlash of three arc minutes through the improved accuracy of its components and the backlash-elimination mechanism. That mechanism is comprised of two sets of internal and planetary gears on the upper and lower levels with the internal gears and planetary gears reduce clockwise backlash; the lower-level internal gears and planetary gears reduce counterclockwise backlash. Available in 1.10 in. (28mm), 1.65 in. (42mm), 2.36 in. (60mm) and 3.54 in. (90mm) frame sizes. |
