The distance from the upper surface of the upper support 271 to the lower surface of the lower support 272 is 30-70 mm. The motor 2 adopts a single-phase four-pole series motor, the distance from the upper bracket 271 to the lower bracket 272 can be set to be 30-70mm, and compared with the existing single-phase two-pole series motor with the same performance, the height of the motor is lower. For example, a two-pole series motor of 7625 or above may have a height of 80mm or more, and a single-phase four-pole series motor for achieving the same performance may have a height of 30-70 mm. Preferably, the distance from the upper support 271 to the lower support 272 is 40-65 mm.

In this embodiment, the first locking portion 2711 is further provided with a shock absorbing pad 6. The shock absorbing pad 6 is disposed on the first locking portion 2711 to reduce the vibration of the motor 2. The shock absorbing pad 6 may be a rubber ring, for example. The fan blade 28 is arranged below the lower bracket 272, and the fan blade 28 is connected with the lower end of the motor shaft 21 and is driven by the motor shaft 21 to rotate. In this embodiment, the rotation of the fan blade 28 generates negative pressure at the bottom of the motor 2, and drives the airflow to flow through the motor 2 from top to bottom, so as to dissipate heat of the motor 2. In other embodiments, the fan 28 may be configured to rotate to drive the airflow to move upward, i.e., blow from bottom to top, so as to dissipate heat from the motor 2.

Referring to fig. 3, an operation control circuit board 51 and a power circuit board 52 are disposed in the motor lower cover 12, and the operation control circuit board 51 and the power circuit board 52 are stacked up and down. The operation control circuit board 51 and the power supply circuit board 52 are arranged in a stacked manner from top to bottom, and the height thereof is low compared to the vertical arrangement of the circuit boards. In the horizontal direction, the operation control circuit board 51 and the power supply circuit board 52 are located at the side of the motor 2. The operation control circuit board 51 and the power circuit board 52 are located beside the motor 2, rather than being disposed up and down with the motor 2, so that the height of the stand 10 can be reduced.

The motor 2 is connected with a power circuit board 52, and a chopper circuit is arranged on the power circuit board 52 and used for changing the input voltage of the motor 2 so as to change the output rotating speed of the motor 2. When the input voltage of the motor 2 is changed through the chopper circuit so as to change the output rotating speed of the motor 2 and meet different rotating speed requirements of different food materials and different processing stages, the input voltage of the single-phase four-pole series motor is reduced, and the output torque is reduced slightly. That is, when the input voltage of the motor 2 is reduced by the chopper method, the output torque of the four-pole series motor is much larger than that of the two-pole series motor of the same performance. That is, when the same voltage is reduced by chopping, the output torque of the two-pole series motor is greatly affected, so that the output torque thereof is greatly reduced, and the output torque of the four-pole series motor is less affected, so that the output torque thereof is reduced to a limited extent. Therefore, the adoption of the four-pole series motor can reduce the blocking risk of the stirring blade 41 under the low-speed operation of the motor 2.
