Introduction to the main parameters of the stepping motor

(110 prefix [cro has many SS heads to confirm the price of Jinan experimental machine]) base number: mainly 35, 39, 42, 57, 86, 110, etc

(2) number of phases: the number of coils inside the stepping motor. The number of phases of the stepping motor generally includes two-phase, three-phase and five phase. The stepping motor used in China is mainly two-phase, and three-phase is also partially used. Japan uses five phase stepping motor more

(3) step angle: the angular displacement of the motor rotor rotating corresponding to a pulse signal. The step angles of the two-phase, three-phase and five phase stepping motors of the sample with the specified width are L.8 °, l.2 ° and 0.72 ° respectively

(4) how to eliminate the error caused by the device in the torque maintaining horizontal tension testing machine: it refers to the torque that the stator locks the rotor when the motor stator winding is connected with the rated current, but the rotor does not rotate. Holding torque is the most important parameter of stepping motor and the main basis of motor selection

(5) positioning torque: refers to the torque required to rotate the rotor with external force when the motor has no current. This torque is one of the indicators to evaluate the performance of the motor. When other parameters are the same, the smaller the positioning torque is, the smaller the cogging effect is, which is more beneficial to the stability of the motor at low speed

(6) torque frequency characteristic: it mainly refers to the pull-out torque frequency characteristic, and the maximum torque that the motor can withstand without out of step when running stably at a certain speed. The torque frequency curve is used to describe the relationship between the maximum torque without out of step and the speed (frequency). Torque frequency curve is an important parameter of stepping motor and one of the main basis for motor selection

(7) rated current: the effective value of motor winding current required to maintain the rated torque
