Q:What is the difference between explosion-proof motor and ordinary motor
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.
Q:Are motors and motors a concept?
A device that converts mechanical energy into electricity. Currently, the majority of consumer power is consumed, so the commonly used motor is basically the motor.
Q:The difference between brushless dc motor and plain dc motor, where is its advantage
Brushless dc motor consists of motor subject and drive, which is a typical electromechanical integrated product. The stator winding of the motor is a three-phase symmetric star connection, which is similar to the three-phase asynchronous motor. The rotor of the motor is attached to the magnetized permanent magnet, which detects the polarity of the motor rotor and has a position sensor in the motor. Drive consists of power electronic devices and integrated circuit, its function is: accept the motor start, stop, brake signal, to control the motor start, stop, and the brake; To accept the signal of position sensor and the positive and reverse signal to control the flow of the power pipe of the inverter bridge to produce continuous torque. Accept the speed and speed feedback signals to control and adjust the speed. Provide protection and display, etc. Because of brushless dc motor based on self-control type operation, so don't like frequency control of motor speed synchronous motor overload start under plus startup winding on the rotor, also won't generate oscillation and step out when load mutation.
Q:What is the difference between a speed reducer and a regular motor?
Deceleration motor called gear motors, are modular combination, at the same time the output torque, 6 (output synchronous speed 1000 RPM), 8 (output synchronous speed 750 RPM), so through the gears or other institutions such as cycloid motor droop down, and the output of the motor speed or torque can meet the actual requirements, the most commonly used the four pole motor, the equipment is used in speed is generally small, motor, the higher the number, the more expensive, general motors is commonly used 4 (output synchronous speed 1500 RPM), is the combination of reducer and motor, gear motor.
Q:What is induction motor? What is the difference between ordinary motors?
Induction motor is the use of electromagnetic induction to rotate the rotor, and the difference between ordinary motor is a coil is the stator, rotor and ordinary motor coil is usually, and brush.
Q:Why does the direct start-up of high power motors affect the voltage of the grid
The ac motor starts with a current of 5 to 7 times the rated current. The effect of the high power motor directly on the voltage of the grid; The main consideration is that a large start current will reduce the voltage of the grid and cause a ripple effect. Normally, the power grid transformer capacity is over 180kVA, and the power of the motor is below 7kW. At present 4-100kw motor multi-purpose delta voltage drop starting..
Q:In the case of ac motor, the voltage will be higher or lower when the voltage is constant
Induction ac motor, power frequency rise will increase the speed, the rising frequency motor inductance, the current will be reduced, current motor temperature rise will decline. When the frequency of the power supply decreases, the motor speed decreases, the electric current is raised by the decrease of the motor's inductance, and the temperature rises.
Q:What is the difference between explosion-proof motors and ordinary motors?
The difference between explosion-proof motor and ordinary motor: Explosion-proof motors are commonly used in inflammable and explosive situations. 2, the seal of explosion proof electrical connection box is better than ordinary motor. The protection level of explosion proof motor is IP55, and the ordinary motor has IPIP23, IP44, IP54, IP55 and IP56, so it can be distinguished from the shape. Explosion-proof electric motor is a kind of motor that can be used in inflammable and explosive factory. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, in textile, metallurgy, city gas, transportation, grain oil processing, paper, medicine and other departments are also widely used. Explosion-proof motor is the main power equipment, which is used to drive pumps, fans, compressors and other driving machines.
Q:In what situations does the step motor lose?
When debugging of PLC is very smooth, then there is one suggestion 1. According to the actual situation adjustment by compensation parameter values, (because of the synchronous belt elastic deformation is bigger, so need to add a certain amount of compensation when changing direction). 2. Due to the characteristic of the stepper motor velocity cannot be too high, especially with large load inertia, suggest velocity under 1 r/s, this impact is small, the same acceleration is too great shock to the system is big, easy to overshoot, lead to no motor positioning between forward and reverse due and certain pause time, if not will overshoot caused by reverse acceleration is too big. Add delay to the logic of the pulse. That's basically all that. It depends on the condition of the scene.
Q:What is the difference between special motors and ordinary motors?
Working principle: Electric motor: turn the electric flow into mechanical energy and turn the external object Generator: using electromagnetic induction to convert mechanical energy into electricity. It's not the equivalence between the motor and the generator! There is a reversibility between the motor and the generator! In the process of use, we combine them to not become a perpetual motion machine because of the conservation of energy.
