Power module and vehicle having the same
Provided is a power module in which a motor and a motor driving unit are efficiently configured and a vehicle having the same. The power module includes a power module case forming an external form; an inverter provided within the power module case and configured to convert a direct current (DC) power into an alternating current (AC) power; an AC power conductor provided in the power module case and connected to the inverter to cause the AC power converted by the inverter to flow therethrough; and a motor provided in the power module case and connected to the AC power conductor to receive the AC power and generate a rotational force.
1. A power module, comprising:
a power module case having an upper portion formed in a rectangular parallelepiped shape and a lower portion formed in a cylindrical shape;
a motor provided in the lower portion of the power module case having a cylindrical shape and configured to generate a rotational force;
an inverter provided in the upper portion of the power module case having a rectangular parallelepiped shape, disposed at an upper side of the motor and configured to convert a direct current (DC) power into an alternating current (AC) power; and
an AC power conductor provided in the upper portion of the power module case having a rectangular parallelepiped shape and formed in an inverted ‘L’ shape to connect the inverter to the motor.
2. The power module according to claim 1 , wherein the AC power conductor is formed such that the AC power conductor connecting the inverter to the motor is shortest.
3. The power module according to claim 1 , wherein the power module case includes a DC power cable connection unit connected to the DC power cable that supplies the DC power.
4. The power module according to claim 3 , wherein the DC power connection unit is disposed at a side of an upper portion of the module case.
5. The power module according to claim 1 , further comprising a capacitor provided in the power module case and configured to smooth the DC power supplied to the inverter.
6. The power module according to claim 1 , further comprising a controller provided in the power module case and configured to control the inverter.
7. A vehicle, comprising:
a plurality of rotatable front wheels;
a front suspension system configured to support the plurality of front wheels;
a plurality of rotatable rear wheels disposed to be spaced apart from the front wheels;
a rear suspension system disposed to be spaced apart from the front suspension system and configured to support the plurality of rear wheels;
a battery disposed between the front suspension system and the rear suspension system and configured to supply a direct current (DC) power; and
a power module disposed at an upper side of the front suspension system, configured to convert the DC power into an alternating current (AC) power to generate a rotational force, and having an upper portion formed in a rectangular parallelepiped shape and a lower portion formed in a cylindrical shape.
8. The vehicle according to claim 7 , wherein the power module includes
a motor provided in the lower portion of the power module having a cylindrical shape and configured to generate a rotational force;
an inverter provided in the upper portion of the power module having a rectangular parallelepiped shape, disposed at an upper side of the motor and configured to convert the DC current power into the AC power; and
an AC power conductor provided in the upper portion of the power module having a rectangular parallelepiped shape, and formed in an inverted ‘L’ shape to connect the inverter to the motor.
9. The vehicle according to claim 7 , wherein the power module includes
a motor provided in the lower portion of the power module having a cylindrical shape and configured to generate a rotational force;
an inverter provided in the upper portion of the power module having a rectangular parallelepiped shape, disposed at an upper side of the motor and configured to convert the DC current power into the AC power; and
an AC power conductor provided in the upper portion of the power module having a rectangular parallelepiped shape, and formed such that the AC power conductor connecting the inverter to the motor is shortest.
