Non-axis motor

Abstract

The invention relates to a motor, in particular to a non-axis motor which is combined with a slurry pump. The non-axis motor comprises a rotor, a stator, a permanent magnet and an enclosure, and is characterized in that the rotor is internally provided with an installation cavity and externally provided with a rotor auxiliary iron, permanent magnetic blocks, the stator and the enclosure in sequence; the permanent magnetic blocks are distributed on the outer end of the rotor auxiliary iron; two opposite positions on the enclosure are respectively provided with a through hole; and one through hole is communicated with an air blower, and the other through hole is communicated with an induced-draught fan. The non-axis motor has the advantages that the motor can be directly installed on a driven device, thus reducing manufacturing cost; the devices can realize synchronous revolving speed and balanced rotation; the structure layout is compact, thereby decreasing the occupied area; the circulating air radiation is adopted, thus ensuring reasonable control of operating temperature, and having good heat dissipation effect; and the motor operation is safe and stable, and saves electric energy.

Description

technical field [0001] The invention relates to a motor, in particular to a shaftless motor used in conjunction with a mud pump. Background technique [0002] Large mud pumps are usually connected to the motor at both ends of the input shaft through the transmission mechanism, that is, the two motors drive the mud pump to work through the transmission mechanism respectively. The shortcomings of this structure are: two sets of transmission mechanisms need to be configured, including couplings, corner belts, motor pulleys, input shaft pulleys, etc., the structure is relatively complicated, and the equipment cost is high; Most of the transmission mechanisms of the equipment are belt transmission. During the installation and commissioning process, it is difficult to adjust the tension of the two angle belts to be completely consistent. During the operation of the equipment, the drives at both ends are likely to be out of sync, which will affect the normal operation of the mud pu...

The shortcomings of this structure are: two sets of transmission mechanisms need to be configured, including couplings, corner belts, motor pulleys, input shaft pulleys, etc., the structure is relatively complicated, and the equipment cost is high; Most of the transmission mechanisms of the equipment are belt transmission. During the installation and commissioning process, it is difficult to adjust the tension of the two angle belts to be completely consistent. During the operation of the equipment, the drives at both ends are likely to be out of sync, which will affect the normal operation of the mud pump and cannot play the role of mud. The efficiency of the pump; the motor runs for a long time, and the frictional heat cannot be effectively dissipated, which affects its service life and high power consumption
