Abstract: A food processor and an electric motor for a food processor. The electric motor includes: a stator core having a ring-shaped stator yoke and a plurality of stator teeth provided at an inner peripheral face of the stator yoke, two adjacent stator teeth defining a stator slot there between, the plurality of the stator teeth defining a stator hole coaxial with the stator yoke, and an outer contour of a radial section of the stator yoke being substantially circular and having a maximum radial dimension D; and a rotor core rotatably provided in the stator hole and coaxial with the stator hole, the rotor core having a maximum radial dimension d, in which 0.4?d/D?0.55.

Abstract: An electric motor includes a front end cover, a rotary output shaft extending through the front end cover from an inner cavity of the electric motor, and a gear transmission mechanism provided inside the inner cavity of the electric motor. The rotary output shaft includes an inner rotary shaft and an outer rotary shaft that are arranged concentrically. The gear transmission is in a transmission connection with the inner rotary shaft and the outer rotary shaft.

Abstract: A food processor and a rotational speed increase control method and apparatus therefor. The rotary speed increase control method comprises the following steps: when the food processor is idle or in a light load state, obtain a rotational speed instruction, analyze the rotational speed instruction to acquire a target rotational speed for a drive motor, and generate a PWM control signal according to the target rotational speed to control the drive motor, during the process of controlling the drive motor, gradually increase the duty cycle of the PWM control signal according to a progressive increment mode until the duty cycle of the PWM control signal reaches 1; and carry out weak magnetic control on the drive motor to quickly increase the rotational speed of the drive motor.
