There are three main reasons for the large axial vibration of the motor: 1. Electromagnetic. 2. Mechanical aspects 3. Electromechanical hybrid aspects
Electromagnetic
Power supply: three-phase voltage (unbalanced, three-phase motor runs under phase loss)
Stator: iron core becomes elliptical, eccentric, loose, winding is broken, ground breakdown, short circuit between turns, wiring error, the...
Usually the spindle shaft is only for speed control, but in some special cases it is also necessary to control the position of the spindle. For example, when automatic tool change is performed on a machining center, when a tool needs to be changed due to technological requirements in boring processing, and when a workpiece is loaded on a lathe, the spindle needs to be accurately stopped at...

Proper motor shaft alignment increases the operating life span of rotating machinery. To achieve this goal, components that are the most likely to fail must be made to operate within their acceptable design limits.
While misalignment has no measurable effect on motor efficiency, correct shaft alignment ensures the smooth, efficient transmission of power from the motor to the driven...
In linear and sliding motion mechanisms, a linear shaft rod plays a crucial role. Without a linear shaft, we wouldn’t complete a sliding mechanism with linear power transmission.
But, the manufacturing and choosing of the appropriate linear shaft can get tricky. Linear shafts can have different structures and be made of various materials, depending on the properties needed.
So,...
It is applied to the motor shaft in many machines. It is generally made by rolling round steel or forgings through its cutting. If the required shaft diameter is relatively small, it can be processed with round steel bars. If the shaft is relatively large, The diameter of the steps varies significantly and can be machined using forgings. In order to save raw materials and improve...
The spline shaft is a kind of mechanical transmission. The flat key, half-circle key, and oblique key have the same function to transmit mechanical torque. There are longitudinal keyways on the surface of the shaft, and the rotating parts on the shaft also have corresponding keyways to keep Rotate synchronously with the axis. While rotating, some can also slide longitudinally on the shaft,...
Because it is integrated with the electric motor, the Electric Spindle Shaft itself can also be regarded as a high-speed electric motor. There can be many different structural methods, such as induction motors, permanent magnet motors and reluctance motors. The key skill is the dynamic balance at high speed.

Transmission Shaft is an Element Used to Transmit Power and Torque
A transmission shaft is a component used to transmit power and torque. Shafts are made in a variety of different shapes and forms, but most tend to have a solid or tubular circular cross-section. The shaft transmitting power directly from the drive device or power source to the load. The shaft can carry gears, pulleys and...
The spindle shaft is a motion shaft that drives the tool or workpiece to rotate on the machine tool to produce cutting motion. According to the driving mode of the spindle shaft, the machine tool spindle can be divided into two categories: mechanical spindle and electric spindle.
The mechanical spindle shaft drives the spindle shaft to rotate through the spindle shaft motor and the...
