Stepper Planetary Gear Motor (H281-1) 28mm

Q: The step motor knows how to subdivide, how do you figure out the number of pulses required to turn a circle: You set 6400, is a revolution of the 6400 pulse, your step distance of step motor is 1.8 ° Angle, without segmentation, is a revolution of the 200 pulse, you set 6400, 32 subdivision.

Q: Step forward motor life calculation method: The life of a step motor is like any other product, depending on the most vulnerable part of the motor, which is the bearing. Hybrid step motor using rolling bearing, the bearing life usually calibration for 3000 hours, the actual practical can reach more than 100 million hours, sometimes 8 normal too. The so-called life 3000 hours is bearing manufacturer, is refers to under the rated load and rated under the conditions of use, motor after 3000 hours of continuous operation, still can reach the factory when the motor parameters, including noise, friction, etc. But this is only the conservative practice of the manufacturer, actually use, don't care too much!

Q: How to select the step motor?: Considering the impact of friction, inertia and velocity, it is recommended to select DMA860H and 86HS85. For details, please communicate with you in detail

Q: The difference between stepping motors: Stepper motor is installed flange type specification, 42 refers to the stepper motor, 42 mmx42mm 56 is similar, the motor should be a hybrid stepper motor, stepper motor is the biggest difference between torsion and interval Angle, determine its general motors fuselage length and diameter of torsion, step away from the Angle of provided by the manufacturer, at present most is given priority to with the hybrid stepping motor, general interval Angle is 1.8 1.2 0.9 degrees, 0.72 degrees,

Q: What are the step motor parameters and characteristics?: It is the moment when the motor is plugged into the motor and the rotor is locked. It is one of the most important parameters of stepping motor, and usually the moment when the motor is moving at low speed is close to the torque. As a result of the stepper motor output torque along with the increase of speed and continuous attenuation, the output power also along with the increase of speed change, so keep the torque has become a measure of stepper motor is one of the most important parameters. For example, when people say 2N. M step motor, in the absence of special instructions, it means to keep the torque at 2N. M stepping motor. DETENT TORQUE: It is the moment when the motor is not connected to the motor, and the rotor's torque is locked. DETENT TORQUE has no unified translation in China, which makes it easy to misunderstand. Since the rotor of the reactive step motor is not permanent magnet, it does not have a DETENT TORQUE. Some features of stepping motor: The accuracy of the step motor is 3-5% of the step Angle, and it does not accumulate. Step 2: the highest temperature allowed in the appearance of the motor. Stepper motor temperature will make the first motor demagnetization of magnetic materials, which can lead to torque decline and even out of step, so the motor appearance allows the highest temperature should depend on different points of demagnetization magnetic material; Demagnetization of magnetic materials, in general, some are above 130 degrees Celsius, some even as high as 200 degrees Celsius above, so the stepper motor appearance in 80-90 degrees Celsius temperature completely normal.

Q: How does the step motor achieve position control: In the control of the step motor, it can be more accurate if handled well. Typically, a step loss occurs when the load is strong, but it can be overcome in certain circumstances: First, it must be enough to choose the step motor power, which is enough torque. 2, the matching of subdivision and rotational speed must be taken into account. 3, the current of the power supply should be sufficient, the current adjustment of the step motor should be more suitable, as far as possible, put in the larger position. Using a controller with a reduced speed control, this can effectively overcome the loss of inertia caused by inertia.

Q: I have a step into the motor, I want to get him to work, what do I need to prepare, about the cost?: Buy a matching motor driver board, and buy a proper control panel, follow the instructions to pick up good line, motor drive software, can be the most simple driver. If you're good at doing it, you can use your own little money to control the board and write your own programs to play with the motors. There are big open source motor drives on the web.

Q: The stepping motor is shaking and the direction is uncertain.: Step motor jitter is usually indicated that your frequency setting is too high, or it is caused by the rising or falling of the wave in the front of the drive

Q: The difference between stepping motor, steering machine, servo motor?: Step induction motor: a ring that converts electrical pulse signals into angular displacement or line displacement. The simple thing is that the Angle and the number of turns are controlled by the electrical impulse signal. So he just depends on the pulse signal to determine how much rotation. There is no sensor, so the stop Angle will be biased. But the precise impulse signal minimized the bias Servo motor: servo control circuit to control the speed of the motor, controlling the rotation position through the sensor. So location control is very precise. And the rotational speed is variable.

Q: The current and voltage of the step motor, inductance: The torque size is directly related to the winding number of current and winding; In the case of constant current, the more winding number (and the greater the inductance), the greater the torque. So you understand that the torque = winding number x current understanding can be used to refer to this formula, but it's not, it's a lot more complicated than this formula. High-speed cases, i.e., voltage frequency conversion quickens, winding back emf get bigger, abate forward current, so the speed of the motor torque will be smaller. As for the problem, I can't sure answer, I analysis is that the high frequency, inductance is big, the greater the current weakening, winding circle number is the same, so the inductor motors when high speed low torque.
