23 High Torque Geared Stepper Motor

Q: What is the step motor: It is often used in the control for program-controlled transformation, also has the power to be used in the mechanical equipment the action transformation.

Q: What is the principle of the three-phase six-step motor?: Torque: once the electricity, will produce magnetic field between the stator (magnetic flux Ф) when the rotor and stator stagger Angle force F and Ф (d/d theta) is proportional to the magnetic flux Ф = S Br * S Br for flux density, S for permeability area is proportional to the Br L * d * L F as the core effective length, d for rotor diameter Br = N, N I/R, I for the excitation winding ampere turn to take the number of turns (current) R magnetic resistance. Torque and motor torque force = * radius effective volume * * flux density is proportional to the number of ampere turns (only consider linear state) as a result, effective volume, the greater the motor excitation, the greater the number of ampere turns on the air gap between rotor is smaller, the greater the motor torque, and vice versa.

Q: What is the difference between step two and three? Commonly used that?: Two facies in the application of the three-phase stepper motor is the biggest difference to different drive, the market is mainly used in two phase stepping motor, three-phase + three-phase stepper motor drives the overall cost is higher than that of two phase, and the same specifications of the three-phase stepper motor output than two phase is small, but it is generally believed three-phase stability is better, but for using digital stepping driving system, such as Britain, shi EZM digital drive, two phase, three-phase there is no difference in terms of running effect and control precision.

Q: Does the stepping motor start a lot?: To look at the power, here is an algorithm for the motor to start the current: Motor starting current impact, and the nature of the load (constant torque and constant power, fan class) and start the way (direct start, since the lotus root step-down start, star triangle, triangle of yanbian, the frequency-sensitive variable resistance and frequency). Typically, the 38/3 ac asynchronous motor is used as an example for the star delta, which can be estimated: The 110KW motor, which is rated at approximately 200A (also can be estimated at 2 times power), At direct start-up, the current is estimated at 6 times the current rating, about 1200A.

Q: Do you choose the step motor or the servo motor?: The step forward and the servo are not afraid to turn around frequently. The problem is speed, you need to be able to move fast and you're not going to be able to move, The other key can't eat to see how much bond and force you have. A 0.5 S90 degree step can also be done. You're looking at the torque. The step usually does not have the rotor stop wobble, the servo is if the parameter is not set up very well. Focus on your control

Q: Is the torque characteristic characteristic of the step motor? Does the servo motor have a moment characteristic curve?: The word "moment frequency" is not very accurate, so it's better to turn the torque, which means the torque changes as the speed changes Usually under rated speed servo motor, can output the continuous rated torque (note can be, how much actual output associated with working state), above the rated speed, can according to the constant power output (can be, the actual output power associated with state, such as your load bearing is small, the natural power is small)

Q: The relationship between the step motor drive and the controller and the encoder: Stepper motor actuator, as power drive, the encoder is stepping motor's speed and position feedback to the controller, the controller according to the feedback information to make decisions and to control the step motor, thus forming a closed loop control system, connect with each other; The step motor is an open loop controlling element which converts the electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.

Q: The step motor of a wire cutter can be locked, but for what reason: The first two answers are possible. If there is a vibration, the control signal has been delivered, the control section can be ruled out, and if there is no reaction, the driver has a problem

Q: What is the meaning of the step motor drive half flow setting and attenuation setting?: The current set 0.5 or 0.8 A, the rest set 50% and half stream, the fine fraction if the speed is slow, set 16 segmentation. The attenuation setting is also set up 50%. The mode of attenuation is the result of the four transistors that have been advanced or delayed in the sequence of the driver output of the step motor. Decay time setting refers to the stepper motor stalling after a few seconds (average 0.5 3 seconds), rated current of the motor supply attenuation, without attenuation 75% 100%, 50%, 25%, and several. Mainly is to reduce the motor stopped noise, be quiet after the motor has stopped, and energy saving. Usually the above function, if the stepper motor drives, motor stop automatically after attenuation function of rated current, it could really set the motor stopped, how many seconds delay (s) into the attenuation function automatically. Stepper motor, is actually a generator, spinning process will produce inductive electromotive force, when applied voltage disappears will sub there will be a braking effect on both ends of the motor winding, not short sub is inertia. This is reflected in high speed characteristics (no braking high-speed connection) or low speed properties (vibration).

Q: What is the difference between a step motor and a 2380v: One is the factory voltage, the other is the family voltage, and the voltage in the work place is different to take a bath
