Two-stage energy storage motor structure with large starting torque

Abstract

The invention proposes a two-stage energy storage motor structure with a large starting torque, and the motor structure comprises a case. The central part of the case is provided with a motor, and twoends of the motor are provided with output shafts. Two sides of the case are respectively provided with an air inlet and an air outlet. The air inlet and the air outlet are each provided with a solenoid valve. The interior of the air inlet is provided with a turbofan I, and the interior of the air outlet is provided with a turbofan II. The turbofan I and / or the turbofan II are / is disposed on theoutput shafts in a sleeving manner. One end of the turbofan I and one end of the turbofan II are installed on the case through bearings. The case is movably provided with a pulling rod, and the pulling rod is connected with a drive unit. The two ends of the drive unit are respectively matched with the other end of the turbofan I and the other end of the turbofan II. The drive unit is connected with the output shafts, and the output shafts are connected with a flywheel energy storage device. The motor structure detects the internal air pressure of a cavity, controls the opening and closing of the air inlet and the cooperative operation of high-speed flywheels according to the demands of different states, achieves the maximum energy storage, and guarantees that the maximum output torque is provided when there is a need.

Description

technical field [0001] The invention relates to the technical field of motor structure, in particular to a motor structure with two-stage energy storage and high starting torque, which can be used in electric vehicles. Background technique [0002] With the increasing development of social production and life, at the same time, the country vigorously advocates a green and energy-saving energy development strategy. As a common power source, motors are used in many fields, such as electric vehicles and construction machinery. [0003] In applications such as electric vehicles and construction machinery, the motor needs a relatively large starting torque when starting, and it is usually started directly or connected to a frequency converter. When the motor starts directly, it needs to provide a large starting current to the motor, and the starting current is usually several times the normal operating current, so the long-term starting process will have a serious impact on the i...

Problems solved by technology

[0005] Aiming at the technical problems that the existing electric motor needs relatively large starting torque to start, the switching of the working state and the long-term low power output will cause unnecessary energy waste, the present invention proposes a two-stage energy storage high starting torque motor The structure collects the energy wasted by the switch of the working state and the long-term low-power output, and releases it again when needed to provide a greater output torque for the motor; at the same time, it can ensure that the motor works in the rated working state for a long time, which is helpful To prolong the service life of the motor
