specific Embodiment approach 1

[0043] Specific implementation mode one: the following combination Figure 1 to Figure 7 To describe this embodiment, figure 1 The schematic diagram of the three-loop control method for the passive torque servo system of the single-stator motor is given. The motor used in it has only one stator. Due to many problems, this embodiment uses a double-stator motor as the loading motor. image 3Shown is a double-stator permanent magnet motor structure in the form of a concentric structure. The double-stator motor has two stators: the outer stator 1 and the inner stator 3; one rotor: the permanent magnet rotor 2. The double-stator motor has a high degree of mechanical integration and torque Large, high torque-to-inertia ratio, large acceleration, small torque fluctuation, high overload capacity, etc., it is a great improvement on the torque / speed performance of single-stator permanent magnet motors, and the existence of the second stator brings great benefits to the drive control sys...

specific Embodiment approach 2

[0088] Embodiment 2: In this embodiment, Embodiment 1 is further described, and the power split ratio m=1. The power split ratio m is determined by the diameter of the inner and outer stators of the double-stator motor and the number of winding turns, and is a fixed value.

specific Embodiment approach 3

[0089] Embodiment 3: This embodiment further explains Embodiment 1, and the double-stator motor driver 7 is realized by using a DSPTMS320F2812 numerical control chip. It is connected with the upper computer through the bus, exchanges data in real time, and realizes human-computer interaction based on the VB interface.

Abstract

The invention provides an energy consumption type double-stator passive moment servo system, and belongs to the technical field of semi-physical simulation. The system aims to solve problems existing in a common loading motor in an existing passive moment servo system. A non-salient pole double-stator motor is adopted to serve as the loading motor, an outer stator converter and outer stator three-phase windings of the double-stator motor are connected with a resistor R respectively in series, the two ends of each resistor R are in parallel connection with a switching tube, and the switching tubes are T1, T2 and T3 respectively; an inner stator converter drives an inner stator three-phase winding; the outer stator converter and the inner stator converter share one direct-current bus; a drive signal of the outer stator converter and a drive signal of the inner stator converter are provided by a double-stator motor drive, a three-loop control mode is adopted by the double-stator motor drive, alternating-axis and direct-axis current set values, provided by current loops, of an outer stator and an inner stator are obtained through a power ratio regulator, output electromagnetic torque is precisely controlled, and meanwhile electromagnetic torque inner loop moment fluctuation is reduced.

Description

technical field [0001] The invention relates to an energy-consuming dual-stator passive torque servo system, which belongs to the technical field of semi-physical simulation. Background technique [0002] In the development of electric motors and electric drives, electric vehicle drives, ship propulsion, aircraft and aircraft steering gear, and underwater vehicles, passive torque servo systems are often used to provide load torque in a semi-physical simulation. Develop the torque loads that the equipment bears under real working conditions and environments. For example, the research on ship electric propulsion technology needs to establish a high-power propulsion motor test system. The propeller load simulation is an important part of the propulsion system research. It requires the motor to simulate the propeller load to work in a special state, that is, its mechanical characteristics and propeller mechanical characteristics In the performance test of the steering gear, the...
