Development of High-Acceleration, Energy-Saving SANMOTION Linear Servo Motor
■Linear servo motors are increasingly demanded in applications that require high-speed operation and highprecision positioning, such as surface mounters and lithography equipment. In recent years, they are growingly used in medical devices for higher precision. The advantage of using them is that they can easily achieve high speed and high precision by directly driving equipment linearly without using a rotary-to-l inear motion conversion mechanism such as a ball screw.
■To improve the speed and precision of customer equipment , it i s es sent ial to improve the thrust characteristics of the linear servo motor that drives the equipment while also reducing the motor size, weight, and energy usage (loss reduction). In addition, the motor size affects the size and mass of the parts used in the motor mounting mechanism. Furthermore, the motor’s heat generation causes thermal expansion in the motor mounting mechanism in equipment, which undermines the precision of the equipment.
■To overcome these challenges, we developed a compact, high-acceleration, energy-saving linear servo motor. The new product is a flat type linear motor with core.
■In this article, we begin by showing the specifications and appearance of the new product. Next, we describe its structure and characteristics and present its features taking an example of an XY cartesian robot.
