Toyo Corporation Launches 'TSB DRIVE Series' All-in-One Motor Torque Test Bench for Miniaturization and High Output of e-Mobility and Industrial Equipment Motors

Toyo Corporation (Head Office: Chuo-ku, Tokyo; President and CEO: Toshiya Takano) will launch the "TSB DRIVE Series" on March 27, 2026. This new model of the company's all-in-one "TSB (Toyo Smart Bench) Series" for motor performance evaluation includes three models—TSBD2000, TSBD1000, and TSBD500—designed for motoring and regenerative testing of small-to-medium motors.

【 Background / Overview 】

The "TSB DRIVE Series" targets torque testing for small-to-medium motors (1.5kW to 5.0kW) used in air conditioning equipment, small mobility, and industrial machinery. It standardizes support for both motoring tests (measuring acceleration/drive) and regenerative tests (recovering power generated during deceleration). Utilizing regenerative energy is directly linked to improved energy efficiency, extended cruising range, and longer system life. Furthermore, by adopting a highly responsive load motor, the inertia of the load device has been reduced to up to 1/8th of comparable class systems. Additionally, real-time load commands at 250µs (microsecond) intervals enable load testing that more closely simulates real-world conditions. This allows for efficient testing across various processes, from development and control design verification to shipping inspections.

With the launch of these new models, Toyo Corporation will further support evaluation testing aimed at the miniaturization and high output of motors in the development of air conditioning equipment, small mobility, and industrial machinery.

As electrification advances, particularly in the e-mobility and industrial equipment sectors, there is a growing demand for smaller, higher-output, and more efficient motors and inverters. In response, Toyo Corporation developed and launched the "TSB Series" in March 2022, providing a complete set of equipment necessary for torque, rotation speed, and efficiency measurements. Since then, the company has expanded its product lineup by customizing solutions to meet user needs and standardizing functions to support a wide range of motor torque tests.

Moving forward, Toyo Corporation will continue to contribute to the improvement of motor performance and the research and development of advanced mobility technologies in the accelerating electric market by expanding the scope of motor performance evaluation and providing an environment where testing can be conducted more easily and efficiently through the "TSB Series."

【 Key Features of the "TSB DRIVE Series" 】

1. All-in-one provision of items necessary for motor torque measurement

Supports evaluation of small-to-medium motors from 1.5kW to 5.0kW. The all-in-one system includes a torque meter, load motor, control panel, load control/measurement software, bench jigs, safety devices, and a measurement instrument wagon, allowing for immediate evaluation upon installation.

2. Reproduction of torque and speed fluctuation loads during a single rotation (depending on motor specifications)

Adopts a highly responsive load motor, achieving up to "1/8th low inertia" compared to brake loads in the same class. Additionally, real-time load commands to the load motor at 250µs intervals enable load testing that is closer to actual machine operation.

3. Connects with power meters and temperature loggers, supporting a wide range of tests with a single software
