Maximum Torque Per Ampere Control. The MTPA Control Reference block computes the d-axis and q-axis reference current values for maximum torque per ampere MTPA and field-weakening operations. The computed reference current values results in efficient output for the permanent magnet synchronous motor PMSM. However this strategy allows achieving the minimization only of the stator joule losses but not of rotor joule and iron losses which could even increase resulting in a.

Maximum torque per ampere MTPA speed control strategy has been widely adopted to achieve high efficiency of an IPMSM drives in constant torque region. Different from conventional MTPA control laws this novel MTPA control law equivalently considers both the. Maximum Ampere Control MA CF Constant Flux Control und MTPA Maximum Torque per Ampere Control können nur verwendet werden wenn die notwendige Spannung nicht größer als die Maximalspannung ist. The paper deals with minimization of supply power and energy for induction motor IM based on maximal torque per ampere MTPA strategy. At first the MTPA current trajectory of IPMSMs is achieved by drawing the constant torque loci in the current plane and finding the nearest points on torque loci to the origin 2. Daher heißt dieses Verfahren Maximum Ampere Control MA.
Different from conventional MTPA control laws this novel MTPA control law equivalently considers both the.
In addition the MTPA and the. This mode of operation is subsequently referred to as the maximum torque per ampere MTA strategy. This paper discusses maximum torque per ampere MTPA and maximum efficiency control methods based on the Volt per Hertz Vf control for an interior permanent magnetic synchronous motor IPMSM. In 9 premade lookup tables are avoided by. Abstract-This paper describes the MTPA maximum torque per ampere control strategy of Salient-pole PMSM permanent magnet synchronous motor and its flux-weaking control strategy. However in this work it is shown that the MTPA control strategy 2 performs sub-optimally as the stator surface temperature and presumably rotor temperature varies.
