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 terminal box type motor conforms to the IP65 standard of ingress protection against water and dust. Available in 2.36 in. (60mm) and 3.35 in. (85mm) frame sizes. |
