- Q: There is a difference between ac frequency conversion and dc frequency conversion
- To compare the differences, you must first understand the structure of the two. In order to realize the dc motor speed regulation, there are several ways: (1) in the winding internal series resistance, the method of reducing I increases the loss of the drag system, the mechanical performance is "soft", and now it is not necessary. (2) regulating the armature winding voltage U, which is by far the best method of regulating speed, has the following characteristics: A) the mechanical properties of the speed adjustment are constant, and the speed landing only changes with the armature voltage. B) to achieve stepless speed adjustment, zero speed adjustment C) because the main flux is constant, the motor rated current is constant, so the speed control process has a "constant torque" characteristic.
- Q: What is the difference between the excitation winding of ac motor and the armature winding?
- Only the synchronous generator and the synchronous motor have excitation winding and armature winding. The general ac asynchronous motor is not excitation winding. Squirrel-cage asynchronous motor points and winding type two kinds big, the same stator winding structure, the squirrel-cage rotor cage bar, wound rotor rotor coil is an external device (can change the rotor impedance to realize variable speed). The "armature winding" is the "main power circuit" of the motor. Which power of the rotor and stator coil is "armature", needless to say, most stator coils are "armature winding".
- Q: Why not use a commutator?
- The difference between an engine and an electric motor is that there is no electric power on the engine, and the motor is connected to the power supply but not necessarily the other
- Q: Why is it that high speed motors rarely communicate?
- High-speed motor power is small, the production of dc easy, power gain, ac motor are rarely of more than 1500 turns, the high speed rotor of the centrifugal force is too large, high power motor generally do not need such a high speed. Series electric motor can be used for both the dc and dc, high speed, at home food processing machine, handgun drill and so on If you use a converter, you can do special high-speed motors, and the price of the converter is much higher than the motor.
- Q: If the motor through reducer drive the load, the load moment of inertia is to convert to the motor shaft, namely, divided by the square of reduction ratio, and, after conversion of moment of inertia of the moment of inertia/motor = inertia ratio?
- In general use ordinary ac asynchronous motor, need not calculate inertia, the characteristics of ac motor is that he didn't have enough output moment of inertia, which is driven too heavy, though the steady-state torque is enough, but the transient inertia is too large, then the motor started to be rated speed, the motor will slow fast first, slowly speed, eventually reach the rated speed, so the driver is not shivering, the control effect is not big. But due to choosing a servo motor, servo motor is depend on the encoder feedback control, so its startup is very rigid, must achieve speed and position of the target, at this time if the amount of inertia to withstand more than motor, the motor will be shaking. So when calculate with servo motor as a power source must fully consider the inertial factor, need to compute movement eventually convert to the motor shaft of inertia, through the torque, moment of inertia calculation start time M = J x B, J is the moment of inertia, B for the angular acceleration, the calculation of the torque M less than the start torque of the motor to achieve smooth start.
- Q: Permanent magnet motor is dc motor and ac motor
- A permanent magnet can be a dc motor or ac motor (for example, a home breeze fan). In the same way, no permanent magnet can be either a dc motor or ac motor, or even an alternating current. In contrast to electric excitation motor, permanent magnet motor, especially rare earth permanent magnet motor, has simple structure and reliable operation. Small volume and light weight; Small losses and high efficiency; Flexible and varied in shape and size of the motor and other significant advantages, and application scope is extremely broad, almost throughout the aerospace, defense, the areas of industrial and agricultural production and daily life.
- Q: How to control ac motors with dc 24V voltage
- Weak electricity controls strong electricity, which is the basic requirement of control. The voltage of DC24V can operate the coil of the relay, and then control the motor's three-phase ac contactor. It can also be used by PLC relay output module to operate the motor's three-phase ac contactor. In the motor start-up and protection circuit, the contactor is the component that controls the engine's stop. High power motor, which can be operation by the frequency converter, passive contact with remote start frequency converter, and drive the passive contact, can also be DC24V dc intermediate relay.
- Q: Calculation method of motor torque
- There is a formula for your problem: Electrical power: P = 1.732 * U * cos phi Torque: T = 9549 times P/n; Power torque = 9550 * output power/output speed Torque = 9550 * output power/output speed P = T * n / 9550 The formulas The relationship between motor power, torque and speed Power = force * velocity
- Q: What is the starting method of ac motor?
- Start with 2. Star - triangle start. 3. Extension start. 4 drop press start.I hope my answer will help you.
- Q: Single phase capacitor ac motor speed regulation why does not have corresponding frequency converter
- Single-phase ac motor from principle is converted by the three-phase ac motor, is just one of the phase is generated by capacitance mobile phase 90 degrees, if meet with frequency conversion governor drive the work by the capacitance of the problem. The variable frequency governor has the input single phase 220v, the output three phase 220v variety, only choose Star/Angle 380v / 220v triphase motor will work.
