What are the step motor parameters and characteristics?

Answer:

Stepper motor is according to the actuator input pulse signal, a signal to perform a step distance, but when dynamic load is too large, easy to throw step, specific parameters to see samples...
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.
Some basic parameters of the step motor: Inherent step distance of motor: It means that the control system sends a pulse signal, the Angle that the motor spins. Motor factory is given a step away from the Angle of value, such as 86 byg250a type motor is given a value of 0.9 ° / 1.8 ° (half step work step 0.9 °, the whole work of 1.8 °), the interval Angle may call it the 'inherent interval Angle motor, it is not necessarily the motor when the actual work of real interval Angle, real interval Angle and drive on. Step motor: It refers to the number of coils within the motor, which are currently used in two phases, three phases, four phases and five phase stepping motors. Step motor phase number is different, it is apart from the different Angle, the general step of the two-phase motor pitch Angle is 0.9 ° / 1.8 ° and 0.75 ° of three-phase / 1.5 ° and 0.36 ° of five phase / 0.72 °. When the driver is not broken, the user mainly depends on the step of the different phase to meet the Angle of the step. If you use a subdivision drive, the "phase number" will become meaningless, and the user simply changes the score on the drive and can change the step Angle. HOLDING TORQUE:
The parameters of the stepper motor a lot, paying special attention to in practical application are stepping motor in different voltage and current, frequency under the condition of different drive torque curve, make sure that the step motor running in the process of the output torque can meet the needs of all kinds of sports equipment, otherwise easy to appear out of step and blocked.
