Minimize the moment of inertia to the limit to accommodate high rotation speeds.
**Features** - The moment of inertia is minimized to accommodate high rotational speeds. - The moment of inertia is extremely small, providing good responsiveness to rapid acceleration and deceleration. Additionally, it is easy to shift the torsional vibration frequency of the shaft system to the high-speed rotation range. - The main spindle rotation part and the body swing part utilize high-precision ball bearings, resulting in extremely low friction resistance, allowing for high-precision torque measurement. - A high-precision load cell is used for torque measurement, allowing for electrical measurement. - Due to its efficient cooling, the main body size is compact and lightweight, requiring no large installation area in the test room. - Safety device sensors for insufficient cooling water pressure and rising drainage temperature are built into the main body. - The installation of automatic control devices is easy, and an interlock system is built in to quickly stop the dynamometer based on abnormal sensor signals from the dynamometer body. - The HL-type dynamometer is adopted for testing high-speed racing engines.
