Abstract

The invention includes a motor controller and method for controlling a permanent magnet motor. In accordance with one aspect of the present technique, a permanent magnet motor is controlled by, among other things, receiving a torque command, determining a normalized torque command by normalizing the torque command to a characteristic current of the motor, determining a normalized maximum available voltage, determining an inductance ratio of the motor, and determining a direct-axis current based upon the normalized torque command, the normalized maximum available voltage, and the inductance ratio of the motor.

Torque limit of PM motors for field-weakening region operation

Patent Royak, Semyon ; Harbaugh, Mark M

The invention includes a motor controller and technique for controlling a permanent magnet motor. In accordance with one aspect of the present technique, a permanent magnet motor is controlled by receiving a torque command, determining a physical torque limit based on a stator frequency, determining a theoretical torque limit based on a maximum available voltage and motor inductance ratio, and limiting the torque command to the smaller of the physical torque limit and the theoretical torque limit. Receiving the torque command may include normalizing the torque command to obtain a normalized torque command, determining the physical torque limit may includemore »« less

Implementation strategies for concurrent flux weakening and torque control of the PM synchronous motor

Conference Monajemy, R ; Krishnan, R

Two implementation strategies for the concurrent control of the mutual flux linkage and torque of a PM synchronous motor is discussed. A vector control system is utilized to provide independent control over the stator current and its angle. The main objective is to maintain a 1 p.u. stator voltage at higher than 1 p.u. speeds by accurately weakening the mutual flux linkage. The maximum permissible torque command for such a system is derived analytically and is shown to be a function of the commanded mutual flux linkage and machine parameters. The first strategy is based on two lookup tables thatmore »« less
Parameters and volt-ampere ratings of a synchronous motor drive for flux-weakening applications

Journal Article Bianchi, N ; Bolognani, S - IEEE Transactions on Power Electronics

This paper deals with the selection of the motor parameters and the inverter power ratings for a permanent-magnet (PM) synchronous motor drive in order to meet a given flux-weakening torque versus speed characteristic. Appropriate combinations of stator PM flux linkage, d- and q-axis inductances, and inverter current rating at a given voltage are derived, in normalized values, as functions of the specified flux-weakening speed range and torque limits. By means of these sets of data, the drive designer can easily individuate and compare all the suitable synchronous motors (defined by the d- and q-axis inductances and flux linkage) and themore »« less

Real Time Flux Control in PM Motors

Technical Report Otaduy, P J

Significant research at the Oak Ridge National Laboratory (ORNL) Power Electronics and Electric Machinery Research Center (PEEMRC) is being conducted to develop ways to increase (1) torque, (2) speed range, and (3) efficiency of traction electric motors for hybrid electric vehicles (HEV) within existing current and voltage bounds. Current is limited by the inverter semiconductor devices' capability and voltage is limited by the stator wire insulation's ability to withstand the maximum back-electromotive force (emf), which occurs at the upper end of the speed range. One research track has been to explore ways to control the path and magnitude of magneticmore »« less

Modeling Reluctance-Assisted PM Motors

Technical Report Otaduy, P J

This report contains a derivation of the fundamental equations used to calculate the base speed, torque delivery, and power output of a reluctance-assisted PM motor which has a saliency ratio greater than 1 as a function of its terminal voltage, current, voltage-phase angle, and current-phase angle. The equations are applied to model Motor X using symbolically-oriented methods with the computer tool Mathematica to determine: (1) the values of current-phase angle and voltage-phase angle that are uniquely determined once a base speed has been selected; (2) the attainable current in the voltage-limited region above base speed as a function of terminalmore »« less
