CONNECTION CABLE 9683 Inverter PC Three-phase power supply Motor CF card ■ What's so special about inverter motors? Inverter motors are indispensable as the power source of industrial equipment The rotation of an induction motor depends on the input frequency, so if this input frequency can be made variable, the rotation can be controlled freely. Development of a frequency conversion technology called an inverter has made it possible to freely control the rotation of motors. In recent years, the mainstream inverter control method is the PWM (Pulse-width Modulation) method. Interval measurement enables the acquisition of perfectly synchronized data CF card ● Conventional measurement method Traditional methods use the average rectified RMS indication (Mean) in order to obtain a component value close to the fundamental wave frequency from a pseudo sinusoidal waveform (fundamental wave + carrier wave) to be input. To measure an accurate fundamental component, frequency analysis was required; however, the conventional processing method was not practical because it could barely perform real-time measurements with FFT as a result of the limited computing power. Mean value ● What is the PWM method? A pseudo sinusoidal waveform (fundamental wave) is comprised of a pulse train called a carrier frequency (at about several kHz to 15 kHz) as the fundamental wave frequency that determines the rotation of a motor. ● Performance evaluation and electrical measurement of motor The axis output of a motor is closely related to the fundamental wave frequency to be input, so an accurate measurement of this fundamental wave component is required to evaluate the input characteristics. Full-wave rectification PWM waveform Mean-value processing & coefficient processing Mean value (average rectified RMS indication value)* * Method to measure RMS values at a single frequency ● The 3390 is capable of measuring the fundamental wave component accurately The 3390 performs this frequency analysis using high-speed harmonic computation processing at an interval of 50 ms and displays the true fundamental wave component. 7 3 To make the best of inverter motor measurements: • Parameters critical to the measurement of motor inputs (outputs on the secondary side of inverters) can be measured and displayed simultaneously.

The 3390 can conduct FFT analyses synchronized to rotation pulses from the tachometer and the motor induced voltage, and the A-phase and Z-phase pulse inputs that allow measuring and detecting the origin of the motor more simply and accurately – fully meeting the needs of the latest motor analysis tests. Example of sensor connection Torque meter Torque value / frequency output Incremental type rotary encoder A-phase pulse output Z-phase pulse output ■ The importance of measuring the electrical angle of synchronous motors The key to the performance of high-performance low-fuel consumption vehicles represented by HEV and EV is the synchronous motor that is used as the power source. The synchronous motor is finely controlled by alternating signals generated by an inverter device (DC to AC conversion) using the electricity from batteries. ● What is a synchronous motor? A synchronous motor rotates in synchronization with the AC frequency. Structurally, the motor is turned by the rotating force at the magnetic pole of the rotator (rotator magnetic pole), which is generated by the rotating magnetic field generated by applying an alternating current to the magnetic field (stator magnetic pole). The rotation speed is synchronized to the speed of the rotating magnetic field, so the *1: Between the primary and secondary sides, between the secondary side and motor output, and between the primary side and motor output *2: If the fundamental frequency varies between the primary and secondary sides, the harmonic analysis can be performed for only one side Encoder A-phase signal Encoder Z-phase signal θ Voltage / current waveform ■ Application 1: “Electrical angle measurement” ○ The voltage / current fundamental wave component “θ” from the machine angle origin can be calculated by performing harmonic analysis of motor input voltage / current by synchronizing to the A-phase signal and z-phase signal of an encoder. ○ A function to perform zero compensation for this phase angle when a motor induced voltage is generated can be used to measure the voltage and current phase (electrical angle) in real time based on the induced voltage when the motor is started. speed can be controlled by changing the speed of the rotating magnetic field (power supply frequency). In addition, high operating efficiency is one of the advantages of the synchronous motor. ● Why is electrical angle measurement necessary? In the case of a synchronous motor, a phase shifting occurs between the stator magnetic pole and the rotator magnetic pole due to a change in the load torque. This shifted angle and the torque force that can be generated by a motor have a close relationship, so it is important to understand this shifted angle (electrical angle) in order to achieve high-efficiency motor control. ● The 3390 provides a more accurate measurement method The 3390 supports the incremental encoder output in addition to the measurement methods of the HIOKI 3194 Power HiTESTER – enabling you to measure this electrical angle more easily and accurately. 9 2 Perform harmonic analysis from the low-speed rotation range of motors • Harmonic analysis from a synchronization frequency of 0.5 Hz Accurate measurements can be performed in the low-speed rotation range of motors without the need of an external clock.
