basic information
The 4-component rotary dynamometer consists of a rotor, stator, connection cables, and signal conditioner. The type of rotor is determined by the required spindle type on the machine side. A piezoelectric 4-component sensor and a 4-channel charge amplifier are integrated into the rotor to measure radial forces Fx and Fy, axial force Fz, and torque Mz. The voltage output from the charge amplifier is digitized and transmitted to the stator. The range selection and power supply for the charge amplifier are transmitted non-contact from the stator to the rotor. There is a gap of a few millimeters between the stator and the machine tool. The signal conditioner controls the measurement system. Additionally, the measurement range can be selected from three options, and measurements can be initiated manually or via a serial interface. The output signal is an analog voltage of ±10V. Data can be recorded using Kistler's DynoWare or compatible data acquisition software.
