Torque motorThe characteristics must be understood, which can keep the tension unchanged, and will not cause the uneven thickness of the wound product; Therefore, manufacturers that need to be applied to this aspect will choose those with soft characteristicsTorque motorAs the working power in the production process; So the motor models are different when we choose, how should we tellTorque motor manufacturerWhat products do we need?
When we make product selection, the first thing we see is the product model and parameters:
The above is a relatedMori machineproducedTorque motorProduct model parameter table. So how to choose according to the parameter table provided by the manufacturer? Let's look down:
1.Model: Each motor production will be marked with the model, such asYLJ63-4-0.5expression Y--Usually table asynchronous motor, ACTorque motorIn fact, it is a squirrel cage type asynchronous motor (divided into synchronous and asynchronous two types,YTable asynchronous);LJ--The first letter of the moment to distinguish it;63--Frame number, used to see the size of the size;4--Representing series;0.5--Torque during gridlock;
2.Frame number: Frame number is to see the size of the size; First we need to be sureTorque motorInstallation in the machine:
Determine the installation method to view the size table of the motor installation, this is a picture of the installation method:
According to the picture of the installation method, the corresponding letters on the right side can be seen according to the installation size table, such as the shaft diameter and width of the motor. If the parameters match, we can use this motor.
3.Number of poles: By the number of poles we can see the corresponding rotation speed,N(Rotational speed)=60*f(Frequency50HZ)/P(number of poles);Torque motorThe relationship between torque, power and speed:T=9500*P/n;T--Torque (unitN.n),P--powerKW),n--Rotational speedr/min),9550Is the calculation coefficient;
According to the speed formula, the following table can be obtained4For example:N=60*50/2, that's it1500turn
2level | 4level | 6level | 8level | 10level |
3000turn | 1500turn | 1000turn | 750turn | 600turn |
4.Torque of gridlock: gridlock--We are referring to the normal power of the motor in the case of rotation, by external force to force it to stop, becauseTorque motorThe characteristics of the motor will not burn out the motor winding at the rated time, so we can see that there is an allowable blocking time at the table; locked-torque--Refers to the torque when the speed of the mechanical equipment is zero (gridlock).
5.Blocked current: the shaft of the motor is fixed and does not rotate, and is energized, and the current at this time is blocked current
