Problems solved by technology

Compared with other types of explosion-proof products, the flameproof shell needs to use higher strength materials, and the products made will appear taller and bulkier.
In addition, the water cooling plate, cooling water tank, heat dissipation water pump, heat dissipation pipeline, antifreeze and other structures used in the permanent magnet frequency conversion motor make the permanent magnet frequency conversion motor need to occupy a large space, and the transportation is inconvenient

Abstract

The invention relates to a safety-increased explosion-proof type frequency conversion and speed regulation all-in-one machine, the safety-increased explosion-proof type frequency conversion and speed regulation all-in-one machine comprises a motor, a frequency converter, a connecting shell and a fan, a first heat dissipation channel is defined by the connecting shell, a heat conduction plate and a motor shell of the motor, and a first air inlet and a first air outlet are formed in the first heat dissipation channel; a second air inlet and a second air outlet are formed in a motor shell of the motor, the second air inlet is communicated with the first heat dissipation channel, and a fan air outlet of the fan is communicated with the first air inlet. The safety-increased explosion-proof type frequency conversion and speed regulation all-in-one machine provided by the invention can be applied to a working condition environment close to combustible gas, and is small in size, light in weight and convenient to transport.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to an increased safety and flameproof type variable frequency speed regulation integrated machine, which is used in a working condition environment close to combustible gas. Background technique [0002] The speed of mining equipment often needs to be adjusted according to the needs of different working conditions. Therefore, variable frequency speed regulation motors are widely used in mining equipment. At present, the implementation of the frequency conversion motor is that the inverter and the motor are placed and installed separately, both of which take up a certain space, and the connecting parts such as cables used to transmit control signals and power signals between the two also take up a certain amount of space. space, and as the length of the cable increases, the signals transmitted between the two are easily interfered by environmental noise, and the transmission ...
