An object of the utility model is to provide a servo motor of asynchronous machine shell type to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an asynchronous machine shell type servo motor, includes motor casing, the fin has been arranged to the motor casing outside, motor casing below and base cooperation, flange has been installed to motor casing's front portion, flange hole has all been seted up to flange's four corners position, the lower part intermediate position of base has the support bar, the base both sides have the linking arm.

Preferably, a plurality of hoisting screw holes are formed in the top of the connecting flange.

Preferably, the connecting arm is provided with a plurality of connecting holes.

Preferably, the motor housing is made of cast iron.

Compared with the prior art, the beneficial effects of the utility model are that: when the asynchronous motor shell type servo motor is used, the shell of the existing stepping motor can be used for reconstruction, a connecting flange is additionally arranged at the front part of the shell, spare holes are formed in a connecting seat, the reconstructed motor shell can be connected with a flange through the connecting flange at the front part and can also be connected through a base at the bottom of the motor shell, the connecting mode is various, the application range is wide, a plurality of hoisting screw holes are formed in the top of the connecting flange, when the motor shell is hoisted, a hoisting bar can be screwed into the hoisting screw holes to play a role in conveniently hoisting the motor shell, meanwhile, the motor shell is cast by adopting cast iron materials, the common servo motor shell is generally made of aluminum materials, has the advantages of light weight and simplicity in processing, but is not suitable for corner installation due to the fact that the aluminum materials are easy to deform and are not suitable for corner installation, the motor shell of the, the original mounting bracket of the servo motor is omitted, the strength of the motor shell is guaranteed, the connecting hole in the connecting arm is used for fixing the base, the supporting bar in the middle of the base plays a role in strengthening bearing, and meanwhile, the supporting bar can play a role in auxiliary connection, a connecting piece can penetrate through the lower part of the mounting surface and is in threaded connection with the supporting bar in a specific mounting occasion, and the connecting strength is strengthened; this device plays reduce cost's effect in the replacement asynchronous machine work progress, does not change the staff to the use habit of motor before the transformation, has servo motor's high performance and asynchronous machine advantage of being convenient for to install simultaneously, has extensive application market.
