Identify more accurate motor control by using motor parameters measured under actual operating conditions in upstream design processes.
PMSM:
Permanent magnet synchronous motors (PMSMs) have been attracting attention in recent years as a type of 3-phase AC motor that can deliver low energy loss and significantly reduced power consumption.
Please prepare the torque sensor and rotary encoder separately.
Identifying Advanced Motor Control
In order to identify advanced motor control, it is necessary to take into account the current dependence of the d-axis and q-axis inductance Ld and Lq, which in the past were treated as constants. The PW6001 can carry out d-axis and q-axis vector analysis of voltage and current during motor operation. Since that data can be used to calculate Ld and Lq in real time, it is possible to measure the current saturation characteristics of motor parameters.
Ld = vq – Ke + ω – R x iq/ω x iq
Lq = R + iq – vd/ω + iq
