What is shaft DC motor?

How Shafts in AC/DC Motors Function. 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.

What is the formula of the diameter of the shaft?

you can find out the circumference by a measuring tape. For example the circumference of the shaft is 600 cm. Then divide 600 to 3.142. The result will be its diameter.

What is the shaft size?

The shaft diameter is defined as the diameter of the hole in the iron laminations that contains the shaft, as indicated with the red arrow in Fig. 1 (and not as the actual diameter of the mechanical shaft, which can be much smaller).

How do you find the shaft diameter of a power?

1. From the formula: power = 2*pi*RPM*Torque/60.
2. Find Torque, the use following to find dia.
3. Torque = pi/16 * Shear Strength * cube of shaft diameter.

How many types of shaft are there?

Types. They are mainly classified into two types. Transmission shafts are used to transmit power between the source and the machine absorbing power; e.g. counter shafts and line shafts. Machine shafts are the integral part of the machine itself; e.g. crankshaft.

How do you calculate shaft design?

Basic Shaft Design Formula

1. M is maximum bending moment on the shaft.
2. r is the radius of the shaft.
3. I is area moment of inertia of the shaft.
4. Input data:
5. Solution:
6. I = pi * r^4 *0.25.
7. = 0.785*r^4……………….. Eqn. 1.2.
8. r= 12.85 mm.

How to calculate the minimum shaft diameters?

The minimum shaft diameters calculated by the torque transmission and torsional deflection methods are essentially the same for Examples 1 and 2. Still, a good approach is to calculate the size both ways, and then use the larger value as the absolute minimum.

How much torque can a hollow shaft transmit?

The amount of torque that a hollow shaft can transmit depends on the thickness of the wall between its inside and outside diameters. A thinner wall cannot handle as much torque as a thicker one. The 3-in shaft in Example 3 was capable of transmitting 1,700-hp and had a wall .5-in thick: (3 – 2)/2 = .5-in.

What is the inside diameter of a hollow shaft motor?

A 200-hp (150-kW), 1,800-rpm hollow-shaft motor has an outside shaft diameter of 3-in (76-mm) and inside diameter of 2-in (51-mm). To determine if this shaft size is sufficient to transmit the required torque, solve the following equation for P:

What if a shaft is transmitting 200 kW at 1200rpm?

Problem: A shaft is transmitting 200 kW at 1200RPM. Find a suitable diameter for the shaft, if the maximum torque transmitted exceeds the mean by 30\%. Take maximum allowable shear stress as 70 MPa. Operating Torque (T Operating) =?
