Q:Is the servo motor to be used as a common motor?
You can use it as an ordinary motor, the premise is the drive still need to use, can be set to Cn001 is 1, speed control, select Cn002.0 is 1, do not use the input node SON control servo, servo power immediately started. The Hn505 is H010A, which selects the internal velocity; Sn201, you can set the speed you want. The two strands of the electric motor, the four line is the power, the three phase four line, like you have done that to the scrap n many RMB, the ninth line is the encoder line,
Q:The ordinary motor is adjusted by the frequency converter
It can exceed the rated speed, but it is best not to be too much, the main fear is that the bearing and rotor will not bear the high speed. The motor exceeds the rated speed, the output of the motor is constant, but the torque decreases. Can you continue to drag your load, depending on whether your load is constant or constant torque,
Q:Which is good for common motor and induction motor?
The common motor and induction motor are the same kind of clicks, and the induction motor is a kind of common motor. 1, the common single-phase capacitor motor, main winding and the auxiliary winding is not the same: more vice winding wire loops, enameled wire line diameter is small, the runtime needs to switch (or main winding) of each winding head, tail to change to.
Q:What kind of fan is explosion-proof motor
First of all, should be clear is general explosion-proof, still be explosion-proof of coal grade. Explosion-proof motors, if applied to EXDI, should be done according to 3836.2,
Q:Precautions for water cooled motor
(1) water-cooled air-cooled motor during normal operation of temperature should not exceed the permitted limits. When running, the personnel on duty should always pay attention to monitor the temperature of each part. (2) monitoring water-cooled air-cooled motor load current. Water-cooled air-cooled motor overload or failure occurs, can cause the stator current surge, water-cooled air-cooled motor overheating. Electrical equipment should have current meter monitor water-cooled air-cooled motor load current, the normal operation of water-cooled air-cooled motor load current shall not exceed the rated current value stipulated in the nameplate. (3) to monitor the change of supply voltage, frequency and voltage unbalance degree. The power supply voltage and frequency is too high or too low, three-phase voltage imbalance will cause current unbalance, can cause water-cooled air-cooled motor overheating or other abnormal phenomena. Current unbalance degree should not exceed 10%.
Q:How does the motor stop
Install a red emergency stop button (commonly known as a large cap) in the control circuit and place it in handy. You need to stop, just click.
Q:What are the characteristics of plateau motors? Why can't the general motors be used for plateau areas
High insulation level, good ventilation and cooling performance, and more adaptability to prevent and prevent the structure of anti-structure. In order to meet the conditions of high altitude, low pressure, lack of oxygen, high temperature, high temperature and bad weather.
Q:The motor does not turn except sound
The motor shaft and shaft sleeve clearance is too large, or motor rotor momentum is too big, a magnetic field when electric motor internal rotor and the stator attraction bruised (commonly known as "chamber"), unable to turn. At this point the electric current will soar, if not handled in time, the machine will burn down.
Q:The abnormal sound of a three-phase machine
First rule out the factors of lack of phase, because motor open phase, a few seconds can be burned motors. In this case, there are several possible: 1, the motor winding fault, lead to motor disorder, internal magnetic field should be quickly find out the reason, simple method is to check the motor phase current balance
Q:What is the difference between explosion-proof motors and ordinary motors?
the excitation control system is reliable by using the brushless excitation, setting the rotary rectifier disc and the static excitation cabinet. It is accurate to be accurate, without impact. The excitation system loses step protection and is reliable, and the whole step is strong. The circuit design is reasonable, the discharge resistance is not hot in the work. Excitation current adjusts the scope width. (3) synchronous machine, ac exciter and rotating rectifier disk coaxial. The rectifying disk is located between the main motor and the exciter, or outside the bearing seat. (4) the hull protection level is IP54. Adopt F class insulation, temperature rise press B. (6) change the traditional water cooling to the upper water cooling, the water cooler on the upper part of the motor. (7) set up an antitide heaters, fixed in the hood of the motor, to be used for heating and moisture-proof during downtime. (8) select the high quality raw materials, electrical and mechanical calculation with a large margin, which can meet the temperature requirements of the running reliability and the increase of an ampere motor. (9) to set up comprehensive monitoring measures; The main junction box is set up for the differential protection of the self-balancing current transformer. The stator winding is buried in the work and the spare platinum-thermal resistance, which is Pt100. A leak monitor to monitor the leak of a water cooler; The two sides of sliding bearings have the on-site temperature display and remote signal terminals. Positive pressure type motor is a type of positive voltage electrical equipment.
