Servo Motors

SKC offers a line of servo motors with unique applications in specific industries. Servo motors provide motion control for ticket vending machines, plain paper copiers, and automatic commercial door locks.

SKC has been designing and manufacturing Servo Motors since 1991. These motors are typically designed in Japan and produced at our leading edge manufacturing facility in China. Other Info: Servo Motors Applications | Servo Motors Specifications

Stepper Motors

Stepper motors are brushless DC motors whose rotor rotates in discrete angular increments when its stator windings are energized in a programmed manner. Rotation occurs because of magnetic interaction between rotor poles and poles of the sequentially energized stator windings. The rotor has no electrical windings, but has salient and/or magnetized poles.

From this definition, it is clear that stepper motors are a digital actuator whose input is in the form of programmed energization of the stator windings and whose output is in the form of discrete angular rotation. It is, therefore, ideally suited for use as an actuator in computer control systems, digital control systems, etc. Control systems employing stepper motors as actuators are known as incremental motion control systems (IMCS).

2 Phase Step Motors

This is a basic step motor wire configuration for most mainstream step motors. When motors are wired in this configuration - 2 phases - they are generally easy to operate, provide step angle and torque performance that can cover a broad range of applications and are generally easy to develop control devices for (e.g. drive controls, etc). Technically, 2 phase step motors operate by providing current to each phase individually in a sort of "switching" function.

2 phase step motors of this type are used in many markets and applications where motion control, positional accuracy and torque are required in a product "system". These markets include medical, office automation, security surveillance, factory automation, PC peripherals (printers, scanners), cellular technology and gaming products.

NEMA step motors

NEMA is a global standard for step motors, generally identifying a stepping motor's physical dimension and not a motor's electrical parameters. It is a frame size standard. NEMA motors include the following frame sizes: NEMA 10, NEMA 14, NEMA 17, NEMA 23, NEMA 34 and NEMA 42. Because NEMA only determines a physical standard and not an electrical standard, NEMA step motors of the same frame size can differ very much from a performance standpoint. Differences can include electronic phases, torque, step angle, speed, step accuracy, detent torque, resistance, inductance, etc.

Applications for NEMA step motors are broad and diverse and include many of the same markets and applications noted above.

NEMA 23 Step Motors

Please see explanation in items 1 and 2 above. One additional thing to note about NEMA 23 step motors is that these are the most common NEMA frame size in the world. Shinano has a very broad and strong line up of NEMA 23 step motors. Applications for this motor can be found in office automation, gaming products, dispensing equipment and cellular technology.
