Product Description:

Provided by Pacific Scientific, the K34HCHJ-LNK-NS-00 hybrid step motor is associated with a high level of reliability and ruggedness. This motor delivers high torque output. The product features a hot housing surface when it is in use. This device features 100 Megohms insulation resistance at 25 VDC. The unit can be used with the manufacturerEs as well as third-party drives with a wide range of current and voltage ratings. It helps in eliminating mechanical gear reduction when it is operated with a direct drive.

This motor owes its high acceleration capabilities to a high torque-to-inertia ratio. The product is characterized by low detent torque harmonics. This device has a smooth micro stepping performance. The unit is designed to meet demanding motion requirements. It is a good cost-effective alternative to servomotors that are used for applications that depend on moderate speed. This motor portrays a non-cumulative angular accuracy of +/-1.5% without load and for one full step. The product is free of any special winding. This device has high demagnetization resistance because of the rare earth magnets in the rotor. Its mounting holes have a diameter of 5.6 mm.

This motor has a high degree of ruggedness. The product encompasses a straight key in its output shaft. This device comes with a detent torque of 65 Nm. The unit also portrays a phase resistance of 0.8 Ohm with a tolerance of +/-10% and a typical phase resistance of 8.9 Ohms. It features a maximum ambient operating temperature of 40 degrees C. This hybrid step motor features high flexibility with support for three types of connection. The product has no interface to connect an encoder for feedback. The device has a frame size of 3.38 inches. This unit can be sized with the manufacturerEs OPTIMIZER Version 3.0 software. It depicts optimal magnetics in a housingless frame.
