SANMOTION PB servo stepper

In the field of industrial automation, there has long been a trade-off between performance and cost between stepper systems and servo systems. Although open-loop stepper systems have low cost and high low-speed torque, they have disadvantages such as out of step, high heat generation, and limited positioning accuracy; The communication servo system has excellent performance, but the price is high and the control is complex. The "SANMOTION Model No. PB" series launched by Sanyo Denki in Japan was born to fill this market gap. This series of products was initially applied to positioning equipment in conveyor systems, as well as short stroke, high-frequency action scenarios that utilize the low-speed and high torque characteristics of stepper motors. In recent years, with the increasing speed and reliability of stepper systems, as well as the demand for servo system replacements, the market's demand for high torque, cost-effective, and high-performance solutions has been growing. In this context, Sanyo Electric has developed the "SANMOTION Model No. PB" series of new products with AC power input. This article will comprehensively analyze product architecture, technical specifications, core innovations, and user functions.
