DRIVE DEVICE

摘要

A heat sink (50) has two heat dissipating blocks (51). Each of the heat dissipating blocks (51) has a wide columnar shape. Each of the heat dissipating blocks (51) has connecting sections (54, 55) on both the ends. In each of the connecting sections (54, 55), a hole that penetrates in the axis direction of a motor (2) is formed. A screw (56) is inserted into the connecting section (54), and the connecting section is screwed to a motor case (10). A screw (57) is inserted into the other connecting section (55), and the connecting section is screwed to the motor case (10) with a cover (110). Each of the two power modules (60), which respectively configure the inverters for two systems, is disposed on each of the heat dissipating blocks (51).
