China Jingdao Machinery & Electronic Co., Ltd. is one of the stepper motors, step motors manufacturer and stepper motor, step motor dealer in China that has patents on the motors and generators design. There isn't any problem with IP protection laws when you buy our generator, motor, engines, diesel, gearmotors and other power supply and motor-driven items, even in strict regions, such as North America and Europe. Our company has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. We'll print custom logos and stepper motor, step motor product documentation in your language, and provide spare parts for easily worn down components. We also can design and deliver OEM/ODM samples in one month.

Inside a stepper motor are four coils of wire located 90 degrees away from each other - i.e. at positions 12, 3, 6, and 9 o'clock. In the middle is the rotor which spins and has permanent magnets fitted around its circumference. As the rotor spins each magnet in turn approaches, passes, and moves away from each of the four coils in turn. A magnet passing a coil of wire causes electricity to flow through that coil and so each of the four coils will have different amounts of electricity flowing through it either one way or the other - alternating current. Since a stepper motor has four coils of wire, it is said to be a four-phase motor. (read more about three-phase electricity (3) here to better understand multi-phase electricity). The advantage of this multi-phase set-up for electricity generation projects is that when one coil has no electricity flowing through it, the next coil will have reached its maximum.

Holding Torque: 0.032 N.m (0.28 lb.in). Step Angle: 0.9°. Voltage: 6.6 V. Current/Phase: 0.4 Amp. Ohm/Phase: 16.5 Ω. Inductance/Phase: 3.5 mH. Flange Size: 39 mm2 (1.54in2). Connection: 6 Lead.
Rotor Inertia: 0.009 kg.m2 (x10^4). Mass: 0.135 Kg. These modules control a bipolar stepper motor (4 wires). They make it possible to carry out a programmable number of steps and manage the slopes of acceleration and deceleration independently of the computer, which can thus perform other tasks during the movement of the motor. One can know at any time number of step carried out. The movement automatically stops when reaching one of two limit-switches. Module with current regulation by chopper. Power supply up to 48 Volts DC m aximum. Limit the heating of the motor and gives performances in terms of acceleration and speed generally much higher than those of XA-298 module.
