In the feed system of machine tool, linear motor is used to drive directly. The biggest difference between the drive mode of the original rotary motor and that of the original rotary motor is that the mechanical intermediate transmission link between the motor and the worktable (trailer) is cancelled. That is to say, the length of the feed chain of the machine tool is reduced to zero. Therefore, this transmission mode is called 'direct drive' or 'zero drive'. Direct drive avoids the shortcomings of reverse clearance, inertia, friction and rigidity in screw drive. The development and application of linear motor system has caused a sudden change in the traditional feeding mechanism structure of machine tool industry. Through advanced electrical control, not only the feeding mechanism has bee...

Servo motor is mainly used in large-scale mechanical equipment, which is the place to control the movement of the whole mechanical equipment. In this way, the quality and after-sale of servo motor is very important, because once problems arise, it will affect the operation of the entire machinery and equipment, resulting in the decline of the overall efficiency of work!Quality is not much to say, with the progress of domestic science and technology development, servo system has made great progress compared with previous years. Although domestic brands are a little less convenient than imported brands, but I believe that the rapid development of domestic technology will bring a higher level of upgrading.Servo motor after-sales is very important, timely and meticulous after-sales will solve ...

The daily maintenance of servo motor is very important, which is directly related to the normal operation of the whole machine and the service life of the servo motor. So daily maintenance and maintenance is indispensable! Next, Senmer Xiaobian will tell you how to maintain and maintain the servo motors in the end! uuuuuuuuuuu1. Use environment should be always dry, motor surface should be kept clean, air intake should not be hindered by dust, fibers and other obstacles.2. When the thermal protection of the motor continues to operate, it should be ascertained whether the fault comes from the motor or the overload or the setting value of the protective device is too low. After eliminating the fault, it can be put into operation.3. Good lubrication should be ensured during the operation of t...

As a professional servo motor manufacturer, many customers will always ask how to match the servo motor reducer? Senmer Xiaobian is here today to clear up the confusion!1. Verify that the rated load torque is less than the rated output torque of the reducer.2. The rated torque deceleration ratio of servo motor is larger than the rated load torque.3. The load is converted to the inertia of the servo motor through the reducer, which should be within the allowable range of the servo motor.4. Verify that the accuracy of the reducer can meet your control requirements.5. The structure and size of the reducer can not only meet the requirements of the equipment, but also connect with the selected servo motor.

First, what is a direct drive motor?Direct drive motor is a kind of direct drive motor which can directly convert electric energy into motion mechanical energy without any intermediate conversion mechanism and directly drive load. This kind of motor adopts 'direct drive technology'.2. Advantages of Direct Drive Motor1. Direct drive. The rigid connection between the motor and the driven workpiece directly avoids the problems of reverse clearance, inertia, friction and insufficient rigidity in the transmission system of the transmission screw, without the intermediate links such as screw, gear, reducer and so on.2. High speed. The normal peak speed of linear motor can reach 5-10m/s; the traditional ball screw, whose speed is generally limited to 1m/s, produces higher wear.3. High acceleratio...

As a domestic servo motor manufacturer, today we want to popularize science and technology about the working principle of servo motor!The word 'servo' derives from the Greek word 'slave'. 'Servo motor' can be understood as a motor that absolutely obeys the command of the control signal: before the control signal is sent out, the rotor is stationary; when the control signal is sent out, the rotor rotates immediately; when the control signal disappears, the rotor can stop immediately.Servo motor is a micro-special motor used as an actuator in automatic control device. Its function is to convert electrical signals into angular displacement or angular velocity of the rotating shaft.Servo mechanism is an automatic control system that enables the output controlled variables of the object's posit...

DC servo motors are divided into brushless and brushless motors.Brush motor has low cost, simple structure, large starting torque, wide speed range, easy control and maintenance, but it is easy to maintain (carbon brush replacement), produces electromagnetic interference, and has requirements for the use environment. It is usually used in cost-sensitive ordinary industrial and civil occasions.Brushless motor has the advantages of small size, light weight, large output, fast response, high speed, small inertia, stable rotation and smooth torque, complex control, intellectualization, flexible electronic commutation mode, square wave or sinusoidal wave commutation, maintenance-free motor, high efficiency and energy saving, small electromagnetic radiation, low temperature rise and long life, a...
