Problems solved by technology

[0005] 2. When the fixed constant speed is high, rake the grass. Because the dead grass is soft and the load is small, the raking effect is good and the work efficiency is high; when the constant speed is low, the grass is raked. low efficiency

Embodiment Construction

[0038] refer to Figure 1 to Figure 8 An embodiment of a lawn rake including a switched reluctance motor of the present invention will be further described.

[0039] A mower comprising a switched reluctance motor, comprising a frame, rake claws 2, and a rake shaft 3 arranged on the frame to drive the rake claws 2 to rotate, and the frame is provided with a shaft for driving the rotary tiller to rotate The switched reluctance motor 4 is connected with a controller 5 for controlling the switched reluctance motor 4 , the controller 5 is connected with a power source 6 , and a switch 61 is connected between the controller 5 and the power source 6 .

[0040] There is no winding in any form on the rotor of the switched reluctance motor 4, the structure is simple and the cost is low, and the effect of dust resistance is good at the same time. To ensure stable operation, through the control of the controller 5, the switched reluctance motor 4 can adapt to the stepless speed change wi...

Abstract

The invention discloses a lawn raker containing a switch reluctance motor. The lawn raker comprises a rack, rake-up fingers and a raking shaft which is arranged on the rack and drives the rake-up fingers to rotate, the switch reluctance motor driving the raking shaft to rotate is arranged on the rack, a controller controlling the switch reluctance motor is connected to the switch reluctance motor,the controller is connected with a power supply, and a switch is connected between the controller and a power supply. Accordingly, by means of the switch reluctance motor, the raking shaft is drivento rotate, and the lawn raker can keep to work stably under the dust and high temperature working conditions.

Description

technical field [0001] The invention belongs to the field of garden machinery, and in particular relates to a mower including a switched reluctance motor. Background technique [0002] The lawn rake is a kind of machine used to rake and loosen the soil. At present, the electric lawn rake mainly adopts series motors, frequency conversion motors and brushless motors. Series motors have large commutation sparks, serious EMC interference, The disadvantages of poor dust resistance and high motor temperature seriously reduce the service life of the motor; the frequency conversion motor has the disadvantages of large size, heavy weight, and small unit output; the brushless motor has the disadvantages of uneven torque output, short working time and high cost, and no The dust resistance effect of the brush motor is not good. [0003] Moreover, the working environment of the rake and loose soil of the electric mower is different, so the following situations will occur: [0004] 1. W...
