Abstract
The utility model provides a kind of integrated fire-proof motor, including an explosion-proof casing, and the housing is divided into three explosion-proof cavitys：One motor cavity, a control chamber and a wire connection cavity, are connected between each cavity by explosion-proof wiring terminal, and the wire connection cavity is connected with outside line；The built-in motor of motor cavity；A control module and U, V, W three-phase drive module are provided with the control chamber, the control module is powered by low-tension supply, and are communicated to connect with high voltage power supply, voltage, current signal for gathering high voltage power supply；The input of U, V, W three-phase drive module is connected with the control module output end respectively, and the output end of U, V, W three-phase drive module is connected with the copper bar of the three phase electric machine 11 respectively.In order to improve the radiating effect of explosion-proof integrated motor, the motor cavity is also provided with a cooling device.Because motor and controller are integrated in inside an explosion-proof casing, circuit and pipeline link are simplified.
Description
Technical field
The utility model is related to electric automobile, more particularly to a kind of integrated fire-proof motor.
Background technology
Due to underground coal mine bad environments, tunnel road surface is rugged and rough, and ramp is more, the gradient is big, in tunnel many dust and
Coal slime, and often have ponding.The electric trackless rubber-wheeled vehicle of current underground coal mine trial operation at home, its transmission system is used mostly
The variable speed scheme of electric-machine directly-driven, by fixed speed ratio reduction box, realizes slowing down increasing and turns round.Such vehicle is due to torque conversion range
Narrow, when in colliery, special operation condition is using having low-speed big starting and climbing, efficiency is low, and current drain is big, and power consumption is higher,
So as to have impact on the continual mileage of vehicle.Because of the limitation of vehicle body space, traditional fire-proof motor and fire-proof motor controller point
Installation is opened, is linked using cable between the two, because vehicle chassis space is limited, installation difficulty.
The content of the invention
To overcome disadvantage mentioned above, the utility model provides a kind of compact conformation, installs simple integrated fire-proof motor.
To reach above goal of the invention, the utility model provides a kind of integrated fire-proof motor, including an explosion-proof casing, the shell
Body is divided into three explosion-proof cavitys：One motor cavity, a control chamber and a wire connection cavity, pass through explosion-proof wiring terminal between each cavity
Connection, the wire connection cavity is connected with outside line；The built-in motor of motor cavity；A control module is provided with the control chamber
With U, V, W three-phase drive module, the control module is powered by low-tension supply, and is communicated to connect with high voltage power supply, for gathering
The voltage of high voltage power supply, current signal；The input of U, V, W three-phase drive module connects with the control module output end respectively
Connect, the output end of U, V, W three-phase drive module is connected with the copper bar of the three phase electric machine 11 respectively.
In order to improve the radiating effect of explosion-proof integrated motor, the motor cavity is also provided with a cooling device.
Motor and controller are integrated in an explosion-proof casing by the utility model explosion-proof electric machine controller integral structure
Inside, simplifies circuit and pipeline link.
Brief description of the drawings
Fig. 1 represents the integrated fire-proof motor block diagram of the utility model.
Specific embodiment：
Describe the utility model most preferred embodiment in detail below in conjunction with the accompanying drawings.
Integrated fire-proof motor as shown in Figure 1, including an explosion-proof casing 100, the housing are divided into three explosion-proof cavitys：One electricity
Machine cavity 10, a control chamber 20 and a wire connection cavity 30, are connected between each cavity by explosion-proof wiring terminal, wire connection cavity 30 with it is outside
Connection；The built-in motor 11 of motor cavity 10；A control module 21 and U, V, W three-phase drive module are provided with control chamber 20
22nd, 23,24, control module 21 is powered by low-tension supply, and is communicated to connect with high voltage power supply, the electricity for gathering high voltage power supply
Pressure, current signal；The input of U, V, W three-phase drive module 22,23,24 is connected with the output end of control module 21 respectively, U, V, W
The output end of three-phase drive module 22,23,24 is connected with the copper bar of three phase electric machine 11 respectively.In order to improve dissipating for explosion-proof integrated motor
Thermal effect, motor cavity 10 is additionally provided with a cooling device.
The integrated motor of the utility model explosion-proof electric machine controller integral structure is with controller in an explosion-proof casing
Portion, simplifies circuit and pipeline link.
