Q:What is the difference between the brake step motor and the step motor?
Stepping motor and servo motor with brake and not with two kinds of brakes, belt brake is a brake on stepper motor, motor sports when it relaxed, it lock motor does not move. The aim is to improve the control accuracy and safety factor for some of the more inertial motion.
Q:Is permanent magnet power saving?
It is impossible to save electricity. The power of the input determines the mechanical power of the output. And the 17KW permanent magnet is unlikely to be used on your shredder, with costs and other factors limiting the use of these places. The lowest cost and most common is the use of three-phase asynchronous motors.
Q:What's the difference between a step motor and a brushless motor?
The step motor can control the Angle of rotation precisely, but no brushless motor is not allowed The motor rotor is a grass-fed structure, neither winding nor permanent magnet. On the rotor of the brushless motor is the rotary rectifier and the excitation winding Brushless motor is used to generate power and power. Step motors are used for precise positioning, such as tool displacement control on machine tools
Q:The problem of speed regulating motor and general motors
Of course must be better than the general motor. On the electromagnetic, due to the variable frequency power supply with accompanying wave current, frequency conversion motor by the special design, can reduce the resulting electromagnetic loss. In addition, the speed control system for motor has higher sensitivity and should minimize its moment of inertia. Speed regulating motor in these areas have special design. Of course also can be used as ordinary motor speed regulating motor, but it won't pay!
Q:What are the characteristics of plateau motors? Why can't the general motors be used for plateau areas
Compared with ordinary motor, plateau motor is adjusted for insulation strength, electrical clearance, temperature limit and anti-halo measures. 1, the increase in elevation causes the insulation strength to decrease: the insulation intensity should be reduced by 8 to 15% for every 1000 metres. 2, the breakdown voltage of the electrical clearance is decreased, so the need to increase the electrical clearance in accordance with the elevations. For high voltage motor, the initial voltage of the corona is reduced, and the anti-stun measures should be strengthened. The cooling effect of air dielectric decreases, the heat dissipation capacity decreases, the temperature rise increases, each increase of 1000M, the temperature rise should increase by 3-10%, so the temperature rise limit should be corrected. The high altitude is unfavorable to the dc motor. Pay attention to the choice of carbon brush material.
Q:What is the difference between a speed reducer and a regular motor?
If you're talking about a speed reducer, you can compare it to a regular motor Deceleration motor called gear motor, gear motor, reducer and motor assembly, are modular combination, common ordinary motor is 4 (output synchronous speed 1500 RPM), 6 (output synchronous speed 1000 RPM), 8 (output synchronous speed 750 RPM), motor, including the most commonly used the 4 pole motor, the higher the number, the more expensive, due to the speed of the equipment is used generally smaller, and the output of the motor speed cannot meet the requirements of actual or torque, so through the gears or other institutions such as cycloid motor droop down, at the same time the output torque, in order to satisfy the needs of speed and torque
Q:Is the washing machine an ordinary motor or DD converter?
The washing machine with DD frequency motor is much smaller than that of ordinary ac motor. That's the answer.
Q:Are motors and motors a concept?
Motor, which contains the meaning of generator and motor; The motor, which is turned by electricity, converts electricity into mechanical energy.
Q:In the case of ac motor, the voltage will be higher or lower in constant voltage, which will affect the motor.
The frequency can affect the speed of the motor, the frequency is high, the motor speed is fast, the frequency is low, the motor speed is slow. Of course, the high frequency of the motor will be higher, but the fan will also be faster, so there is basically no effect.
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
