Shenzhen stepper motor wholesale / Guangdong wholesale stepper motor stepper motor is an electrical pulse into the angular displacement of the actuator. Plainly speaking: When the stepper drive receives a pulse signal, it will drive a stepper motor to rotate in the direction of setting 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; at the same time you can control the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed control. In three stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB) is generally phase permanent magnet stepper, torque and smaller, step angle of 7.5 degrees or 15 degree; the reaction is generally a three-phase stepper 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 stepper mean the combination of a 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 stepping motor most widely used.

Hybrid stepping motor driver power supply voltage is generally a wide range (eg SC3660MA supply voltage is 16 ~ 60VDC), the power supply voltage is usually based on the work of the motor speed and response requirements to choose. 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, as this may damage the drive. Power supply current is generally based on the drive output phase current I to determine. If using a linear power supply current is generally preferable to I, 1.1 to 1.3 times; if switching power supply, power 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 (eg SC2440MA drive current 0.1A ~ 4A adjustable), and the subject of a stepping motor allows each motor phase current is the maximum rated current through, so When the drive current can not exceed the current adjustment motor rated current (set principle is: when the motor is driven by the normal work load without losing steps premise of the smaller the better). Holding torque (HOLDING TORQUE) refers to the stepper motor power but did not rotate, the stator locked rotor torque. It is one of the most important parameters of the stepper motor, usually a stepper motor torque at low speed torque to keep close. As the stepper motor output torque with speed constant attenuation, output power varies with increasing speed, so the 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.
