pMOTION

 

 
＜Automatic motor parameter measurement＞
Simply set the basic information (*1) and the motor parameters (*2) are automatically measured.
The system also checks the motor efficiency, optimises the Id/Iq settings and creates a torque　N-T map.
The system is highly effective in determining the design validity required at the prototype stage of motor.

※1 Number of poles and maximum current and voltage.
※2 Resistance, induced voltage and characteristics of inductance value depending on current, (Ld/Id, Lq/Iq).
 

 
＜Simple operation significantly reduces preparation time for the motor drive＞
Map file is commonly used in motor drive, and The creation of map file requires the measurement of motor parameter and measurement of torque at different speeds, currents, phase angles and etc. with motor temperature monitoring.

All measurements by manual operation will take up a lot of time.

pMOTION reduces the preparation time for the motor drive by measurement automation.
 

 
＜Data acquired by sweep operation can be displayed into a graphs according to the application＞
Once data has been acquired by sweep operation
(※1.), it can be freely displayed in a graph according to the application within the range of the data.The vertical and horizontal axes can be easily set. For example, by setting efficiency and loss on the vertical axis and current, phase angle and carrier frequency on the horizontal axis, the motor’s characteristics and trends can be checked visually.※1 Measurements performed while changing the speed, current, phase angle, etc. while driving the test motor.
 

 
＜Measured losses can be displayed indivisually into iron loss, copper loss and mechanical loss＞

pMOTION-Complete can separate measured losses into  iron loss, copper loss and mechanical loss.

 
The data required to separate the losses can be taken in a series of measurement processes of motor parameters, and after measurement in sweep operation, the losses of motor and inverter can be displayed for each rotation speed and current value.
