What is the shaft of a motor?
The shaft in a motor is a cylindrical component that extrudes out from the motor and its housing. The purpose of the shaft is to convert energy from the motor into the end use application. Precision pins and shafts operate as a function of speed vs torque.
How do you tighten a motor shaft?
To tighten the motor shaft, loosen the allen screws on the retaining ring, press firmly on the motor shaft, while pressing on the retaining ring, and tighten the allen screws in the retaining ring. This makes the end play on the motor tighter but does not completely eliminate the end play.
What makes the shaft of the motor spin?
The magnetic field produced by the armature interacts with a stationary magnetic field produced by either PMs or another winding (a field coil), as part of the motor frame. The force between the two magnetic fields tends to rotate the motor shaft.
What is the purpose of shaft?
The term shaft usually refers to a component of circular cross section that rotates and transmits power from a driving device, such as a motor or engine, through a machine. Shafts can carry gears, pulleys and sprockets to transmit rotary motion and power via mating gears, belts and chains.
What material should I use for a shaft?
Materials. The material used for ordinary shafts is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used. Shafts are generally formed by hot rolling and finished to size by cold drawing or turning and grinding.
What is end play on a shaft?
End play is the total distance the shaft can move between the two thrust bearings and is sometimes called float, thrust bearing clearance or axial clearance. As end play becomes larger, the unloaded (slack) bearing will see a larger gap.
How do I stop my shaft from moving?
1) Rely on press-fit bearings to fit well enough to not move. 2) Use a shaft collar with set screw right outside the bearing. 3) Use a pin through a drilled hole in the shaft. 4) Thread the ends of the shaft and use a lock nut.
Which is the horizontal bearing on a motor?
The fixed bearing in the horizontal position is usually the drive end bearing and is locked axially by the outer race housing on the outboard side and the inner back cap. If the motor is to be mounted with a shaft down orientation, no additional axial locking steps are necessary.
Can a motor be mounted on a vertical shaft?
Further, if the inner race is axially locked to the shaft by a locknut or snap ring, no additional steps are necessary when mounting the motor in a vertical shaft up or shaft down orientation. If the inner race of the fixed bearing is not axially locked to the shaft, a locknut or snap ring will need to be added.
Where is the fixed bearing on a Drip Proof motor?
Figure 1 illustrates a drip-proof horizontal motor mounted vertically shaft down and with a drip cover. The fixed bearing in the horizontal position is usually the drive end bearing and is locked axially by the outer race housing on the outboard side and the inner back cap.
How is the stability of a stepping motor determined?
Stepping motors1, 2 are devices which convert electrical pulses into mechanical movements. When power is applied to the stepping motor, it assumes one of n stable positions. The number of stable positions is determined by the number of coil phases in the motor.
