A step into an electric motor can have two step angles, such as 3 degrees / 1.5 degrees. What does that mean?
Refers to the inside of the motor coil set number, at present there are two phase, three-phase, four commonly used phase, five phase stepper motor. The motor phase number is different, the interval Angle is different, 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 °. Stepper motor parameters can improve performance, increase phase but the structure of the stepper motor and drive power supply will be more complex, costs will increase. (3) HOLDING TORQUE (HOLDING TORQUE) :
Motor inherent interval Angle: it said control system each hair a step pulse signal, motor rotation Angle. 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 was 1.8 °), the interval Angle may call it the 'inherent interval Angle motor, it is not necessarily the actual step motor work pitch Angle, the actual interval Angle and drive on. (2) the number of phase stepper motor
Also known as the maximum static torque, is rated static electricity flow in applying of the stepping electric motor shaft, and does not produce maximum torque of continuous rotation. It is one of the most important parameters of the stepper motor, usually when the stepper motor in low speed torque close to holding 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 2 n. m of stepper motor, in the absence of special specification refers to the holding torque is 2 n. M stepping motor.
