Problems solved by technology

However, due to fundamental changes in the air inlet and outlet of the series-excited motor used on the electric rotary tiller, high noise is generated at the high speed of the motor, which cannot meet the safety requirements of the electric rotary tiller, which has seriously restricted it. Production and sales of electric rotary tillers
For this reason, many manufacturers and people of insight have specially developed and developed, but so far no ideal products have come out.

Abstract

The invention discloses a series excited motor for a motor-driven rotary cultivator. The series excited motor for the motor-driven rotary cultivator comprises a motor cylinder (1), a stator (2), a rotor (3), a centrifugal fan (4), a left case (5), a right case (6), an air inlet grid tray (7) and a center cover (8), wherein the air inlet grid tray (7) is fixedly connected with the left case (5) and the right case (6), the left case (5) and the right case (6) are provided with an air inlet channel (16) which is communicated with the air inlet grid tray (7), a cooling channel (15) which is communicated with an inner cavity of the motor cylinder (1) is arranged on the upper portions of the left case (50) and the right case (6), an air outlet channel (17) is arranged between the left case (5) and the center cover (8), the air inlet channel (16) is communicated with the cooling channel (15), the cooling channel (15) is connected with the air outlet channel (17) through the inner cavity of the motor cylinder (1), and a fence air outlet (18) which is communicated with the air outlet channel (17) is arranged on the left case (5). By adoption of the structure, the series excited motor for the motor-driven rotary cultivator has the advantages of being simple and reasonable in structure, good in cooling effect, low in noise, and capable of meeting safety requirements for the motor-driven rotary cultivator, and the like.

Description

technical field [0001] The invention relates to a series-excited motor, in particular to a series-excited motor matched with an electric rotary tiller. Background technique [0002] Series excitation motors have been widely used in electric tools. The rotation speed of series excitation motors is generally very high, ranging from as low as 10,000 revolutions per minute to as high as more than 30,000 revolutions. It includes the left casing and the right casing. , motor barrel, stator, rotor, centrifugal fan, middle cover, the centrifugal fan is fixed on the rotor, the left and right casings are provided with air inlets at the rear, and the front is provided with air outlets; when the motor is powered on, the rotor rotates, and the center of the centrifugal fan High air pressure is formed, low air pressure is formed on the outer edge, air flows, the centrifugal fan sucks in cooling air from the air inlet, cools the motor and discharges it from the air outlet, the motor is coo...
