In order to conveniently adjust the output rotating speed of the motor, a speed reducer is arranged on the motor, so that the whole system structure occupies a large space, and higher voltage is required to be provided to realize the operation of the whole system during use, and the power consumption of the whole system is greatly increased.
The invention provides a double-speed conical rotor motor, which aims at the defects of large power consumption and complex structure of the existing motor, and as shown in figures 1 to 3, the invention provides a double-speed conical rotor motor, which comprises a machine shell 101 and a braking system arranged on the machine shell 101, wherein the inner side of the machine shell 101 is provided with a rotor 102 and a stator 103, the appearance of the rotor 102 and the inner cavity of the stator 103 are conical, the stator 103 is composed of a first magnetic pole and a second magnetic pole, an isolation protection layer is arranged between the first magnetic pole and the second magnetic pole, the first magnetic pole and the second magnetic pole are respectively provided with a power output end, the first magnetic pole and the second magnetic pole are respectively connected with different control systems, the first magnetic pole is 4 poles, the winding number of turns is 4×0.95-1.20mm, the coil is 10-20, the second motor is 16 poles, the winding number of turns is 3×1.00-1.30mm, the coil is 10-20, the outer diameter of the stator 103 is 327mm, the stator height is 200-220mm, the number of turns of the stator is 44, and the stator is 44 slots of the rotor is 48. In the invention, the first magnetic pole and the second magnetic pole form a motor stator, and are matched with a rotor to form two power output systems, and the two power output systems are respectively passed through. In the invention, the motor leads are connected with the joints of the control system by 6 joints, so that the two magnetic poles are respectively connected with the two control systems, one of the two magnetic poles is used as a fast system, and the other one is used as a slow system.
In the invention, the first magnetic pole is 4 poles, the speed is 1400-1500r/min, the second magnetic pole is 16 poles, the speed is 375r/min. The first magnetic pole is used as a fast pole for connecting a load under a light load condition, and the second magnetic pole is used as a slow pole for connecting the load under a full load condition. The first magnetic pole and the second magnetic pole are respectively connected with the power output end, so that the power output end and the second magnetic pole can be controlled by different control systems. When the motor is in full load, the motor is in a slow speed, and the motor is in a fast speed when in light load, the power is low when being used for light load, compared with the existing motor, the power consumption is relatively small, the required current is relatively small when in light load, and when in use, the motor can be connected with a corresponding small-specification circuit control element, so that the use efficiency of the whole motor is higher, and the motor is more energy-saving.

The model of the pull rod can be selected according to the specific output power of the motor, and the pull rod can be broken when the load exceeds the rated power, so that the problem that the motor burns out when the load exceeds the rated power is avoided.
Through adopting sleeve pipe on the output shaft to cooperate with output gear, when making the sleeve pipe rotate along with the output shaft, the pull rod on the sleeve pipe drives output gear synchronous rotation, when the overload appears, under the shearing force effect, makes the pull rod fracture, can make the motor be idle running state this moment, and then can avoid the motor to burn out because the overload appears the problem.
Example 2:
when the conical rotor motor runs, the air gap magnetic field of the conical rotor motor generates axial magnetic pulling force, and the braking spring is compressed, so that the fan braking wheel is separated from the braking ring on the motor end cover, and the motor can rotate freely. When the power is off, the axial magnetic pulling force disappears, and the rotor moves axially under the thrust of the brake spring, so that the fan brake wheel compresses the brake ring to generate friction force, the motor is forced to stop rapidly and bind the rotor, and accordingly the lifted heavy object is prevented from falling down, and safety is guaranteed.

Because of the inertia, the rotor continues to rotate when the motor is de-energized.
When the output gear and the sleeve synchronously rotate under the action of the pull rod, the motor normally operates, when the motor is overloaded, the pull rod is broken, the sleeve and the output shaft synchronously rotate, the output gear and the outer tube stop rotating, and at the moment, the brake pipe on the sleeve can synchronously rotate along with the sleeve. In the embodiment, because the rotor can have axial movement when the motor is started or stopped, the fan brake wheel and the side brake ring are separated from each other when the motor is started, and the brake pipe positioned at one side of the output shaft moves along with the axial movement of the sleeve, so that the brake piece at the brake end and the brake piece on the baffle edge are separated from each other, and the motor can normally rotate at the moment; when the motor is powered off, the axial magnetic pulling force disappears, so that the fan brake wheel and the brake ring at the side are rubbed with each other, the fan brake wheel presses the brake ring to force the motor to stop, and at the moment, the brake pipe at one side of the output shaft moves axially along with the sleeve, so that the brake piece at the brake end is pressed on the brake piece on the stop edge, the rear end cover side and the output shaft side of the motor can realize immediate braking, the motor can stop rapidly, and further, the hoisted heavy object can be prevented from falling.

When springs with different lengths are selected, the positions of the wedge blocks are also changed relatively, and at the moment, the brake pipe is driven by the wedge blocks to rotate relatively, so that the position of the brake pipe can be finely adjusted, the distance between the inclined planes of the tooth structures on the braking ends of the brake pipe and the inclined planes of the tooth structures on the blocking edges is changed relatively, and under the condition that the rotating speed of the rotor is changed at a constant speed, the contact time of the brake blocks on the inclined planes of the two parts is also changed relatively.
When the motor is used, the wedge blocks are propped into the wedge grooves by the springs, when the springs with different lengths are replaced, the corresponding brake rings can be pushed by the wedge blocks to rotate, and the distance between the inclined surface of the brake end and the brake blocks on the inclined surface of the baffle edge can be synchronously adjusted in the relative rotation process of the brake rings, so that the contact time of the brake blocks on the two parts can be correspondingly adjusted, and the time required by motor stalling can be further adjusted.
