H ybrid St e ppe r M ot ors MOTION CONTROL PRODUCTS hybrid stepper motors are widely used in laboratory and medical equipment, printing machines, pumps, vending machines and a multitude of other applications. Breakdown of Hybrid Stepper Motor Part Number: Frame size/ Diameter (mm) Motor type: ST- standard STH- high torque Winding type Number of lead Shaft type: wire: 4, 6 or 8 S- single shaft D- double shaft o J- step angle 0.9 o Q- step angle 3.6 Customisation Options: Shaft Extensions All motors can be supplied with single or double ended shaft to customer request. Shaft length and other dimensions can also be modified on demand. Number of Leads All motors can be supplied with 4, 5, 6 or 8 leads and if required a connector can be provided on our motors to customer request. Winding Code Since each customer request can be different, we list only our standard products in this catalogue. However, we will be happy to quote other variants to your request. Holding Torque Holding torque is measured with two phases supplied at the rated current. The enclosed technical specifications are therefore typical. Our stepper motors can be supplied with or without brakes, encoders, sensors and gearboxes etc. Please contact our technical sales team for more details or application needs. (*** Each customer request for special shaft, leads, fixings etc. will be allocated a unique product code/identifier.) All data & information in this section is subject to change without notice.
