| Abstrak/Abstract |
The permanent magnet synchronous motor
(PMSM) consists of two types, namely surface mounted PMSM
(SPMSM) and interior PMSM (IPMSM). IPMSM has the
potential to generate a greater torque than SPMSM due to
its torque reluctance. To exploit this potential, a comparison
of two control methods is conducted, namely ZDAC (zero d
axis current control) vs MTPA (maximum torque per ampere)
control. Testing between these two control methods was carried
out with variations in speed and load, and it was found that
ZDAC could not maximize reluctance torque, because of that
limiting the torque capability. MTPA control is applied to
optimize efficiency. Compared to ZDAC or Id = 0 A, MTPA
control can produce maximum electromagnetic torque with
smaller stator current values. Therefore, in the constant torque
region or below the base speed, the IPMSM is controlled with
MTPA to obtain better efficiency in motor operation. |
