● Conventional measurement method
■ 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.
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.
In recent years, the mainstream inverter control method is the PWM (Pulse-width
Modulation) method.
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.
Full-wave rectification
Mean-value processing & coefficient processing
Mean value (average rectified RMS indication value)*
* Method to measure RMS values at a single frequency
PWM waveform
● 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.
●
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.

Electrical angle measurements are indispensable for dynamic characteristics analysis of motors.
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.

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.
■
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.
● 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.
● 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
● 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.

●
Interconnected system of solar power generation and power conditioner
● The 3390 supports a long list of measurement items including the specific
ones required.
Electrical energy generated from the solar power generation is DC electrical energy, so it needs
to be converted to AC electrical energy to be used by connecting to the utility grid. The device
to convert direct current to alternating current is the power conditioner. In particular, to sell
electrical energy by connecting to the utility grid, the performance of the power conditioner is
important, so the method to evaluate the performance is specified by the national standards.
The 3390 can measure ripple factor and evaluate and analyze through simultaneous
measurements.
