摘要
Disclosed is an apparatus for controlling a rotation speed of a motor, a motor and a food processing equipment. The apparatus includes: a rotation speed feedback circuit and a rotation speed control loop; the rotation speed feedback circuit comprises a rotation speed inducing unit configured to induce a current rotation speed of the motor and output a rotation speed detection signal, and a resistance adjusting unit configured to adjust a total resistance of a resistor unit of the rotation speed control loop according to the rotation speed detection signal; the rotation speed control loop comprises the resistor unit, a first capacitor, a first controllable switch and a second controllable switch.
