1. According to the type of working power supply: it can be divided into DC motor and AC motor. 1) DC motors can be divided into brushless DC motors and brushed DC motors according to their structure and working principle. Brushed DC motors can be divided into: permanent magnet DC motors and electromagnetic DC motors.

1:11 alarm, control the power supply undervoltage, control the power inverter on P. The voltage between N is lower than the specified value. There are defects in the internal circuitry of the driver, etc. 2:12 alarm, control power supply overvoltage, control power inverter on P. N voltage exceeds the specified value, ...

1. Servo motor pulse control mode In some small stand-alone equipment, the use of pulse control to achieve the positioning of the motor should be the most common application method, this control method is simple and easy to understand. The basic control idea: the total pulse amount determines the motor displacement, and the pulse frequency determines the ...

Mechanical 1. Bearing The bearing clearance on the lead screw housing is too large after wear, or the bearing roller elements and cages are severely worn due to the lack of grease in the bearing, resulting in excessive loads. After bearing wear, the clearance is too large, which will cause the coaxiality error between the center of the motor rotor and the center of the lead screw.

Motor FAQs Generator overheating: If the stator voltage is too high, the iron loss will increase; The load current is too large and the power factor is too low, which increases the excitation current of the rotor and causes the motor to heat up; The three-phase load current of the generator is unbalanced: If the three-phase is unbalanced, it may cause the motor speed to be unbalanced.

· They offer significant cost-effectiveness · They provide smoother operation · they are very efficient and tend to reduce energy costs · can optimize thermal management by embedding the motor into the machine · They offer improved servo performance and therefore improved production ...

1. Please check the motor power line to confirm whether there is a short circuit in the phase wire of the motor 2. If there is no short circuit in the phase line of the motor, it is determined that the internal power tube problem of the driver is determined

1. Bearing failure is one of the most common motor failures. As the most important consumable part in servo motors, more than half of the failures of servo motors are usually caused by bearing problems. Its specific manifestations are varied, from jitter and abnormal noise when the motor rotates to the jamming of the motor shaft. Value...

The main components of the motor include: 1. a frame; 2. an iron core; 3. a winding; 4. an end cover; 5. a bearing; 6. Centrifugal switch or starting relay and PTC starter; 7. a nameplate. 1 frame The frame structure varies depending on the cooling method, protection type, installation method and purpose of the motor.

1. The basic design principle of user-centered In the design process of the system, the designer should grasp the characteristics of the user and discover the user's needs. In the whole development process of the system, it is necessary to continuously solicit the opinions of users and consult with users. The design decision of the system should be combined with the user's work.

1. Excessive load: Confirm whether the connected load exceeds the rated load capacity of the drive. The load is too large and needs to be reduced appropriately to ensure that the current is within the allowable range. 2. The driving system parameter setting is incorrect: check whether the driver parameter setting is correct. 3、 ...

1. AC motors are cheaper to manufacture. 2. With the development of vector frequency conversion technology, it has been possible to simulate direct current with frequency conversion motors 3. Compared with DC motor, it has enough advantages in simple structure, easy maintenance, low environmental requirements, energy saving and improved productivity.

(1) Azimuth share gain Sets the share gain of the azimuth ring adjuster. The higher the set value, the higher the gain, the greater the stiffness, and the smaller the azimuth lag under the same frequency command pulse. However, too large a value may cause vibration or overshoot. The parameter values are determined by the detailed servo ...

(1) Wiring should be done with the power supply OFF, and if the output line is in contact with the power supply when the power is turned on, the output circuit may be damaged. (2) If the wiring is incorrect, the internal circuit may be damaged, so pay full attention to the polarity of the power supply when wiring. (3) If and high-voltage lines, ...

Reasons for the shutdown of the speed up Buke motor due to contamination: 1. Bearing lubrication failure or bearing surface damage Contaminants can disrupt bearing lubrication and damage bearing surfaces. This will cause the friction to generate heat. If the problem cannot be solved, the increased heat may cause the bearing and the ...
