Abstract
The utility model discloses a water-cooled AC frequency conversion asynchronous traction motor which comprises a rotor, a stator and a flange mounting structure. The water-cooled AC frequency conversion asynchronous traction motor provided by the utility model adopts a V-shaped mounting structure and flange connection, thereby having the advantages of simple structure, firmness and durability, and strong impact resistance; when the motor operates, the torque pulsation is low, the noise is small, the rotating speed limit is high, no position sensor is needed, and the operation is reliable.
Description
Technical field
The utility model relates to a kind of AC variable frequency asynchronous traction electric machine, especially relates to the AC variable frequency asynchronous traction electric machine of a kind of water-cooled.
Background technology
Requirement when motor performance fully satisfies the pure electric automobile driving cycle.When low speed, should have big torque and overload capacity.When running up, have big power and broader permanent power bracket.There are enough power performance to overcome the various resistances of car load, guarantee that it has good starting, the energy recuperation when acceleration performance and travel speed and realization braking.
The utility model content
The purpose of this utility model provides that a kind of torque pulsation is low, and noise is low, and the rev limit height does not need position transducer, the AC variable frequency asynchronous traction electric machine of reliable water-cooled.
The technical scheme that the utility model is adopted for achieving the above object is: the AC variable frequency asynchronous traction electric machine of a kind of water-cooled comprises rotor, stator and flange mounting structure.
Also be provided with inlet opening and apopore on the described stator.
Described motor adopts the V-shape mounting structure.
The AC variable frequency asynchronous traction electric machine of the utility model water-cooled adopts " V " font mounting structure and flange to connect, make simple in structure, sturdy and durable, strong shock resistance.During the motor operation, torque pulsation is low, and noise is low, and the rev limit height does not need position transducer, and is reliable.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the AC variable frequency asynchronous traction electric machine structural representation of the utility model water-cooled;
Fig. 2 is the AC variable frequency asynchronous traction electric machine V-shape of a utility model water-cooled mounting structure schematic diagram.
Embodiment
As depicted in figs. 1 and 2, the AC variable frequency asynchronous traction electric machine of this water-cooled comprises rotor 1, stator 2 and flange mounting structure 3, also be provided with inlet opening 4 and apopore 5 on this motor stator, motor adopts V-shape mounting structure, this motor rated power 90kW, peak power 180kW, rated speed 1479rpm, frequency conversion scope 1～140Hz, motor pole number are 4 utmost points, rated voltage 380V.For guaranteeing motor equal energy operate as normal in various adverse circumstances, the degree of protection of motor is had relatively high expectations, and require with smaller volume, rated power that output is bigger, in the maximum power that keeps reducing under the prerequisite that the electric automobile starting is quickened and the low speed climbing capacity is constant motor, thereby reduce the capacity of inverter, the requirement peak power is 2 times of rated power, and peak speed is more than 3 times of rated speed.For realizing this target, the heat load of motor improves a lot than common electric machine, and adopts water-cooling structure, is strict with manufacturing process, and motor adopts " V " font mounting structure and flange to connect, make simple in structure, sturdy and durable, strong shock resistance.
