Motor Calculation Index Cards

Motor Sizing Calculations This section describes certain items that must be calculated to find the optimum motor for a particular application. Selection procedures and examples are given. Selection Procedure First, determine certain features of the design, such as drive mechanism, rough dimensions,

Sizing an index drive can be extremely complicated, but as long as the correct steps are taken the correct model can be chosen. In sizing a rotary index table, most customers have a design of tooling established as a 3d model in a design software. It is possible to have the software provide the inertia in the mass properties.

The speed range for the PS geared motor with a gear ratio of 36 is 083 rmin. 3 Calculate the Required Torque T M Nm Refer to formula. Calculate the Load Torque T L Nm Friction load is negligible and therefore omitted. The load torque is assumed as 0. T L 0 Nm Calculate the Acceleration Torque T a Nm

An index table is a common mechanism found in many manufacturing processes. Each position or index contains a different process necessary for completion of a product. Need Help?

Positioning operation Fill in the fields, if any Rotor inertia. J O. ozin kgm 2. Gear ratio. i If the rotor inertia and the gear ratio are unknown, the acceleration torque will be calculated with an inertia ratio of 51 see the motor selection tips that will appear on the result window for the detail.

Proper sizing of a motor requires that 3 criteria must be met torque, load inertia, and speed. For the first part of this Motor Sizing Basics series, I will be explaining what load torque is, how to calculate it for specific application examples, and how it fits into the torque requirement for the application.

The motor data calculator app is split into 3 modules Motor Data available for low voltage Three phase and Single phase applications - Based on HP and Line voltage you will see approximate ratings for motor FLA and wire size as well as component sizes for Starters, contactors, breakers and fuses both for Enclosed devices as well and open

These forms calculate the necessary Torque, Speed, Stopping Accuracy and System Inertia important when selecting a proper motor for the application. Call our experts for any assistance needed 1-800-GO-VEXTA 468-3982 M-F 730am CST to 500pm PST.

decel_motor max it decel 4. Calculate the Inertia of the System. Once we know the angular acceleration of the motor, we need to calculate the inertia of the load connected to the motor. In this case, we can approximate the index table inertia using the formula for a solid cylinder. J index_table m index_table r index_table 2

motor data. Typical Single Phase amp Three Phase Motor Data Provides typical FLA, SC protection, conductor size, and motor starter information. gt
