As is known to all, the synchronous belt has a certain tension, the use of time is long, more or less will lead to a decline in accuracy, and CNC opening machine precision requirements are strict. Therefore, all kinds of accessories should be reasonably distributed.

1. Guangdong CNC cutting machine operation is generally heavy load and high precision: its characteristics are that the torque required to move the load is often far more than the torque capacity of the servo motor itself. And through the reducer to do servo motor output torque forward, it can be useful to deal with this problem.

2. Forward torque: The way of output torque forward may choose to directly increase the output torque of the servo motor, but this way is not only necessary to use valuable high-power servo motor, the motor also has a more robust structure, the increase of torque is proportional to the increase of the control current, at this moment, the choice of larger drivers, power electronic components and related mechanical and electrical equipment specifications, The cost of the control system will increase significantly.

3. Increase the use of power: in theory, the power of the forward servo motor is also the way to output torque forward, by increasing the speed of the servo motor twice to make the power density of the servo system twice forward, and do not need to increase the driver and other control system components of the specification, that is, do not need to increase the additional cost. And this needs to be distributed through the planetary reducer to achieve the intention of forward torque. Therefore, the development of high power servomotor is necessary to allocate the use of reducer, rather than eliminate it.

4. Forward application performance: It is understood that the improper matching of load inertia is one of the biggest reasons for servo control instability. For large load inertia, the inverse square ratio of deceleration ratio can be used to allocate the best equivalent load inertia, so as to obtain the best control response. So from this point of view, the planetary reducer is the best match for the control response of the servo.

5. Increase the service life of equipment: planetary reducer can also be used to deal with the motor low speed control characteristics of the attenuation. Because the control of the servo motor will be due to the decrease in speed, resulting in a certain degree of attenuation, especially in regards to the stability of signal capture and current control at low speed, it is particularly simple to see. Therefore, the selection of deceleration function to make the motor with higher speed.

6. Drop equipment cost: From the concept of cost, it is assumed that 0.4KW AC servo motor distribution driver, need to consume a unit of equipment cost, with 5KW AC servo motor distribution driver is necessary to consume 15 units of cost, but if the selection of 0.4KW servo motor and driver, distribution of a group of reducer can reach the cost of 15 units to end the matter, Save more than 50% of operating cost.
