The efficiency of motor and life-span.
In order to solve the above problems, the utility model discloses a kind of motor in electric automobile system for detecting temperature, including temperature
Sensor, signal processor, wireless base station apparatus are spent, wherein, temperature sensor is arranged on motor, for obtaining motor temperature
Signal；Signal processor is connected with temperature sensor, for handling motor temperature signal, obtains motor real time temperature；
Wireless base station apparatus is connected with signal processor, for transmitting wirelessly motor real time temperature.
Further, motor in electric automobile system for detecting temperature also includes the power supply module being connected with signal processor.
Further, the number of temperature sensor is 2, is arranged at the optional position of motor.
Compared with prior art, the utility model includes advantages below：
It can continue, be reliable and stably detect motor real time temperature, the longevity is used to protect motor safety, to extend motor
Life.
Brief description of the drawings
Fig. 1 is a kind of motor in electric automobile system for detecting temperature structural representation according to the utility model embodiment one；
Fig. 2 is a kind of motor in electric automobile system for detecting temperature structural representation according to the utility model embodiment two.
Embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings and tool
The present invention is further detailed explanation for body embodiment.
Fig. 1 is a kind of motor in electric automobile system for detecting temperature structural representation according to the utility model embodiment one.
As shown in figure 1, motor in electric automobile system for detecting temperature 1 (in dotted line frame) includes temperature sensor 11, signal processor 12, nothing
Line dispensing device 13, wherein, temperature sensor 11 is arranged at 20 on motor, for obtaining the motor temperature signal of motor 20；Letter
Number processor 12 is connected with temperature sensor 11, for handling motor temperature signal, obtains motor real time temperature；Wirelessly
Dispensing device 13 is connected with signal processor 12, for transmitting wirelessly motor real time temperature.
When motor in electric automobile 20 works, the temperature of on motor 20 measurement motor 20 of temperature sensor 11 is arranged at,
Obtain the motor temperature signal of motor 20；The signal processor 12 being connected with temperature sensor 11 to motor temperature signal at
Reason, obtain the motor real time temperature of motor 20；Signal processor 12 sends motor real time temperature to wireless base station apparatus 13,
The can of wireless base station apparatus 13 sends motor real time temperature to the part with radio receiver or and wireless receiving
It is further processed in the device of device connection.This makes it possible to persistently, reliably and stably detect motor real time temperature, with
Just protect motor safety, extend motor service life.
For example, it is exactly that motor is received by the radio receiver 31 being connected with entire car controller 32 in the present embodiment
Real time temperature is simultaneously sent in entire car controller 32, and the can of entire car controller 32 is to motor real time temperature can to motor
Operational mode adjusts or alarmed.
Wherein, signal processor 12 can be single-chip microcomputer either FPGA or dsp chip.
Certainly, to realize that the function of detecting system still needs to be equipped with ancillary equipment and circuit, such as circuit power supply and letter
The power supply module (not shown) that number processor 12 connects.The circuit structure of the power supply module of the present embodiment is in the prior art
Belong to mature technology, will not be repeated here.
Fig. 2 is a kind of motor in electric automobile system for detecting temperature structural representation according to the utility model embodiment two.
As shown in Fig. 2 in the present embodiment, unlike embodiment one, motor in electric automobile system for detecting temperature includes 2 temperature and passed
Sensor (11 and 11 '), is arranged at the optional position of motor 20, and remaining is essentially identical with embodiment one.2 temperature sensors (11
With 11 '), the optional position of motor 20 is arranged at, is such as separately fixed at diverse location (such as inner cap of opposed separation in motor 20
Shell or drive end bearing bracket), signal processor 12 obtains the motor temperature signal that 2 temperature sensors (11 and 11 ') collect respectively, enters
Row processing, calculate the average for the motor temperature signal that two temperature sensors are collected.In the present embodiment, the electricity that will calculate
The average of machine temperature signal is as motor real time temperature.
Motor in electric automobile system for detecting temperature provided by the utility model, the temperature of monitoring motor in real time is not only able to,
But also can be more accurate, it is easy to adjust existing operational mode according to actual conditions.
A kind of motor in electric automobile system for detecting temperature provided by the utility model is described in detail above, herein
