Q:What is the difference between a servo motor and a direct drive motor?
These two are not a concept Servo motor means that this motor is driven by high frequency pulse driven by servo actuator, which can achieve fixed Angle, fixed speed and fixed torque output. He's talking about the type of motor. A direct drive motor is a direct and rigid connection between the motor and load, without any transmission or coupling in the middle. He's talking about how the motor is used. The servo motor can be connected directly to the load or through the transmission device load. The dc motor can be a servo motor or other motor.
Q:The difference between high voltage motor and general motors
A high voltage motor is defined by a voltage difference. For example, the high voltage motor is considered to be 1000V, 380V, 660V for low voltage motor. A general motor is a relative special motor. Such as drag pump, fan, compressor, crusher and so on. A high voltage motor is a motor that is rated at 1000V. The usual use is 6000V and 10000V voltage, which also has a voltage rating of 3300V and 6600V due to the different power grids in foreign countries. High voltage motor is due to the motor power is proportional to the product of the voltage and current, so the low voltage electrical power increases to a certain degree (such as 300 kw / 300 v) current limited to allow bear ability of the wire is hard to do big, or too expensive. High power output is required by increasing voltage. High voltage motor has the advantage of power and high impact ability. The drawback is that inertia is hard, starting and braking are difficult.
Q:Which is good for common motor and induction motor?
Washing machine motor, its main winding and vice winding circle number, enameled wire line diameter is the same, the main switch, deputy winding can change steering, quite convenient, this is the main difference between both. Look at the washing machine motor
Q:Precautions for water cooled motor
The principle of clean water clean without impurities, he from the water pump of high pressure cavity, namely outlet introduction part on the outside of the motor cooling water rinse, then back to the low pressure chamber of the pump, the pump inlet, so can bring heat away due to no fan motor, the motor temperature constant. Winter must also be used, if water shortage can burn the motor. Upstairs is the submersible motor, which is a different thing
Q:What's wrong with the rotary roller
It's possible that the roller card is dead You turn the drum manually and look at the ready
Q:The difference between pump motor and general motor?
The difference between pump motor and ordinary motor is mainly the shell of the motor and its protection, the oil pump motor casing is sealed explosion-proof type.
Q:What is the solution to other circuit boards when the servo motor is turned on
On the servo drive power reactor with servo filter, and the circular filter, harmonic suppression measures, such as zero phase filter or is to add the device to the output of the servo driver try.
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.
Q:Why is electric motors not rotating? Everything else is good.
The causes of motor does not turn more Not only can be a good motor hall do you want to check the controller of the motor wiring sequence
Q:The problem of single chip machine controlling motor
Single chip computer control machine: The dc motor is spun by the interaction of two magnetic fields. The structure shown in figure, the following page on the stationary part (stator), equipped with a pair of stationary dc excitation main pole N and S, furnish the armature iron core on the parts (rotor). There is a gap between the stator and the rotor. Placed on the armature iron core of the two conductors are joined by A and X armature coil, coil head end and respectively connected to the two circular arc form at the end of the copper, the copper is called the commutator segment. The commutator segment is insulated from each other, and the integral part of the commutator is called the commutator. The commutator is fixed on the axis of rotation, and the commutator is insulated from the rotor. A pair of fixed, fixed brush B1 and B2 are placed on the commutator, and when the armature spins, the armature coils are connected to the external circuit through the commutator and the brush.
