Toyo Corporation (Headquarters: Chuo-ku, Tokyo; President and CEO: Toshiya Kohno) will launch all three models of the 'TSB STEP' series ('TSBS022/P', 'TSBS340/P', and 'TSBS070/H') on Wednesday, April 8, 2026. This series is a new model of the 'TSB (Toyo Smart Bench) Series,' an all-in-one motor torque test bench manufactured by Toyo Corporation, specifically designed for evaluating stepping motors. By adopting our proprietary 'Low-Inertia Load Unit' and realizing a highly manageable electromagnetic brake system, it supports pull-in/pull-out tests ranging from 100 mN·m (millinewton-meters) to several N·m, as well as high-speed pull-out tests exceeding 10,000 rpm. These tests were difficult to perform with the conventional thread-and-weight method. We aim to support the advancement of stepping motor evaluation technology and product development in the motion control field. [Background / Overview] Stepping motors have a simple structure and allow for highly accurate positioning control, leading to their expanding adoption in a wide range of fields, including 3D printers, medical and analytical equipment, and robot peripheral mechanisms such as robot arms. In recent years, against the backdrop of market expansion for products adopting these stepping motors, there is a growing demand for performance improvements such as higher speeds, higher torque density, and lower vibration. Furthermore, compared to servo motors, it has become increasingly important to quantitatively understand the performance limits of stepping motors within their output bandwidth right from the design stage. Conventionally, the 'pull-in/pull-out characteristics' evaluation, conducted as part of stepping motor performance testing, has widely utilized thread-based devices that apply load using a thread and weights. However, users have pointed out several issues: the measurement accuracy depends on the operator's skill in handling the thread, the thread sometimes breaks during measurements for high-tor
