A cooler for electronic devices provides cool air to the inlet sides of the heat sink by using a radial blower with blades located around air outlets of the heat sink. This blower is driven by a brushless DC electric motor. The motor has an opening in the center allowing for the transfer of incoming air to the center of the heat sink. The rotors outer circumferential arrayed poles are rigidly secured to the frame of the radial blower. The stator of the motor is rigidly secured to the heat sink and has an opening in its center. The stator comprises circumferential arrayed coils on circuit board material. When the current flows through the stator coils, the coils acquire a magnetic polarity. The poles of the rotor and stator coils attract and repel depending on the polarities. The cool air comes simultaneously from opposite sides of the heat sink. For this reason the heat sink has a divider located approximately in the middle of the heat sink fins. The blades of the radial blower are located around the air outlets on the heat sink. Because the ambient air is drawn in from both sides of the heat sink the air path length through the heat sinks channels is effectively halved. This results in an increased cooling ability for the heat sink because of the increase in temperature differentials.

In a rotary electric system, a switch member includes at least one of a first switch and a second switch.

The second switch is connected between the neutral point and a low-side electrode of the direct current power source. A controller works to turn the switch member off and on thereby switching control of the multiphase inverter between full-wave driving mode and half-wave driving mode. The full-wave driving mode allows the controller to drive all of the high-side and low-side switching elements per phase of the multiphase stator windings. The half-wave driving mode allows the controller to drive any one of the high-side switching element and the low-side switching element per phase of the multiphase stator windings.
