A single instrument can measure the voltage, torque, number of revolutions, frequency, slip rate, motor power, and electrical angle necessary for motor analysis.
It is possible to measure all data at the same time, and to perform data acquisition and characterization at the industry's fastest 50ms.
In addition, it is possible to accurately detect the origin of the motor, and to easily measure the A-phase and Z-phase pulse inputs corresponding to the incremental encoder, and to more accurately measure the electrical angle that is important for motor analysis.
No external clock is required to be able to analyze 05hz 5kHz harmonics.
step1.Connect voltage lines and current sensors.
step2.Connect the output of the torque gauge and incremental encoder to the input port of the optional motor.
ch a torque input port The torque output of the torque meter.
CH B rotary signal input port Phase A pulse output of incremental encoders.
The Z-phase pulse output of the incremental encoder at the ch z rotation signal input port.
step3.When the motor is not energized, the motor is rotated from the load side to measure the induced voltage generated by the input port of the motor.
step4.With the phase zeroing function, the phase difference between the rotating input signal and the fundamental component of u1 is zeroed.
step5.Power up the motor to rotate and measure.
The phase is measured with the reference voltage induced, so that all parameters can be measured.
