SC stepper motors wholesale - Shenzhen high price of SC stepper motor stepper motor is an electrical pulse into the angular displacement of the implementing agency. Plainly speaking: When stepping driver receives a pulse signal, it will drive a stepper motor to set the direction of rotation of a fixed angle (and step angle). You can control the number of pulses to control the angular displacement, so as to achieve accurate positioning purposes; and you can control the pulse frequency to control the motor rotation speed and acceleration to achieve speed control purposes. In three stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB) permanent magnet stepper usually phase, torque and smaller, step angle of 7.5 degrees or 15 degrees; Reaction Stepper generally three-phase, can achieve high torque output, step angle of 1.5 degrees, but the noise and vibration are great. In Europe and other developed countries, the 1980s have been eliminated; hybrid stepping mean the combination of permanent magnet and reactive advantages. It is divided into two phases and five-phase: two-phase step angle of 1.8 degrees and five-phase step angle of 0.72 degrees. Application of this stepper motor most widely used.

Hybrid stepping motor drive power supply voltage is generally a wider range (eg SC3660MA supply voltage of 16 ~ 60VDC), power supply voltage is usually based on the work requirements of the motor speed and response to selection. If the motor operating speed higher or faster response to the request, then the voltage values ??are high, but note that the ripple voltage can not exceed the maximum input voltage of the drive, it may damage the drive. Power supply current is generally based on the drive output phase current I to determine. If a linear power supply current is generally preferable to I, 1.1 to 1.3 times; if the use of switching power supply, supply current is generally preferable to I, 1.5 to 2.0 times in a simple way how to adjust the rotation direction of the two-phase stepper motor power just after? The motor and drive wiring A + and A- (or B + and B-) can be reversed. Hybrid stepping motor drive current is generally designed to drive a wide range (such as SC2440MA drive current 0.1A ~ 4A adjustable), while the subject of the stepper motor phase current of the motor to allow the maximum rated current through each, so When the drive current adjustment current does not exceed the motor rated current (setting principle is: when the motor to drive the load to work under the premise of not losing steps as small as possible). Holding torque (HOLDING TORQUE) refers to the stepper motor power but is not spinning, the stator locked rotor torque. It is one of the most important parameters of the stepper motor, stepper motor usually torque at low speed torque to keep close. As the stepper motor output torque increases with the speed constant attenuation, output power varies with increasing speed, so holding torque has become one of the most important parameters to measure the stepper motor. Such as, SC57HB76 motor is 1.5Nm In the absence of special note is to keep torque 1.5Nm = 15Kg / cm Shenzhen double-Technology Electronics Co., Ltd. / SC stepper motors wholesale - Shenzhen high-quality SC stepper motor price
