More Information
Summary:A heating cooker includes a heating chamber, a heating portion, a brushless motor, a body control circuit, a DC power supply circuit, a motor control circuit, and a safety device. The brushless motor drives a rotary drive mechanism included in the heating portion. The body control circuit outputs a drive signal for the brushless motor. The DC power supply circuit supplies DC power to the brushless motor. The motor control circuit controls the driving of the brushless motor in response to the drive signal. The safety device includes a rotation detection element to detect the rotation state of the rotor of the brushless motor and output a rotation detection signal, and a switch for blocking a power supply line connected to the DC power supply circuit. The safety device controls the switch in response to the rotation detection signal and drive signal.
