The biggest difference between step motor and general motors

Stepper motor is different from common motor's biggest stepper motor can well control the motor

rotation Angle;Stepper motor is a kind of electrical pulses into angular displacement of the

actuator.Popular point:when the stepper driver receives a pulse signal,it is driving a stepper motor

according to set the direction of a fixed Angle (and the step Angle).You can by controlling the pulse

number to control the amount of angular displacement,so as to achieve the purpose of accurate

positioning;At the same time you can control the pulse frequency to control motor rotation speed and

acceleration,so as to achieve the purpose of speed control.2.What kinds of stepper motor points?

Stepper motor in three kinds:permanent magnet (PM),reactive (VR) and hybrid (HB) permanent magnet stepping,generally for two phase,torque and volume is small,step Angle is 7.5 or 15 degrees

commonly;Reactive step for three-phase commonly,can achieve high torque output,stepper Angle of 1.5 degrees commonly,but noise and vibration are very big.In Europe and the United States and other developed countries have been eliminated in the 80 s;Hybrid stepping refers to a mixture of permanent magnet and the advantages of reactive.It is divided into two and five phase:two phase stepper Angle of 1.8 degrees commonly and five phase stepping Angle of 0.72 degrees.The application of the single phase induction motor stepper motor is more widely.

3.What is HOLDING TORQUE (HOLDING TORQUE)? HOLDING TORQUE (HOLDING

TORQUE) refers to the stepper motor power but no turns,locked rotor TORQUE of the stator.It is one of

the most important parameters of step motor,stepping motor at low speed torque close holding

torque.Because of the stepping electric machine along with the increase of speed and continuous

attenuation,the output torque output power also along with the increase of speed change,so keep the

torque has become a measure of stepping motor is one of the most important parameters.,for

example,when people say 2 n.220v ac electric motorsm of stepper motor,in the absence of special specification refers to the holding torque is 2 n.M stepping motor.4.What is the DETENT TORQUE? DETENT TORQUE is refers to the stepper motor under the condition of no electricity,locked rotor TORQUE of the stator.DETENT TORQUE at home there is no uniform way of translation,to make you misunderstanding;As a result of the reactive stepping motor rotor is not a permanent magnetic material,so it does not DETENT TORQUE.5.How much precision stepper motor for? Cumulative? General precision of the stepper motor step Angle of 3- 5%,and do not accumulate.6.The appearance of stepper motor temperature allowed? 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 electricalmotor1.blogspot.com 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.
