Problems solved by technology

[0004] However, in the conventional motor drive device described above, the motor, the coil switching section, and the power converter are accommodated in separate housing sections and placed separately, so that the motor, the coil switching section, and the power converter are housed in each of the housing sections. dead space may form between
In this case, it is difficult to save space

Embodiment Construction

[0021] Embodiments will now be described with reference to the drawings.

[0022] First, refer to figure 1 Schematic structures of the vehicle 100 and the motor drive section 10 according to this embodiment are described.

[0023] Such as figure 1 As shown, the vehicle 100 includes: a vehicle body portion 101 ; a motor drive portion 10 provided in the vehicle body portion 101 ; and a battery portion 20 connected to the motor drive portion 10 . The motor drive unit 10 is an example of a "motor drive device".

[0024] The motor drive unit 10 includes an inverter 1 , a smoothing capacitor 2 , a motor 3 , a coil switching unit 4 , and a controller 5 . The inverter 1 is an example of a "power converter".

[0025] The inverter 1 is configured to convert DC power input from the battery section 20 into three-phase (U-phase, V-phase, and W-phase) AC power to output the AC power to the motor 3 . The inverter 1 has DC input terminals TP1 and TN1 connected to the battery section 20 a...

Abstract

The invention relates to a motor drive device and a vehicle. The motor driving device includes: a motor including a high-speed driving coil and a low-speed driving coil; a coil switching portion arranged in a direction along a rotation axis of the motor with respect to the motor; a power converter in a direction where the rotation shafts intersect; and a plurality of case parts that accommodate at least the motor, the coil switching unit, and the power converter. The plurality of housing parts are coupled to each other.

Description

technical field [0001] The invention relates to a motor drive device and a vehicle. Background technique [0002] Generally, a motor drive device including a motor having a high-speed drive coil and a low-speed drive coil is known. Japanese Patent Laid-Open Publication No. 2010-017055 discloses a motor drive device including: a motor having a high-speed drive coil and a low-speed drive coil; a coil switching section that switches the connection state of the two coils of the motor; and Inverter (power converter) connected to the motor. [0003] In the conventional motor drive device including the motor, the coil switching section, and the power converter disclosed in the above-mentioned Japanese Patent Laid-Open Publication No. 2010-017055, the motor, the coil switching section, and the power converter are usually housed in separate housing sections. and placed separately. [0004] However, in the conventional motor drive device described above, the motor, the coil switchi...
