Stepper Motors

Rare earth magnets and optimized rotors designed for maximum torque, and high efficiencyStators with maximum winding fill for lower temperatures, long life and maximum torqueLarge ball bearings, also optimized for short repetitive moves to ensure long life.

A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.

Stepper motors, with their ability to produce high torque at a low speed while minimizing vibration, are ideal for applications requiring quick positioning over a short distance. Stepping technology allows for the use of an open-loop controller – simplifying machine design and lowering total cost compared to a servo motor system.

MOONS' designs and manufactures three main types of stepper motors: Hybrid Stepper Motors, Permanent Magnet Stepper Motors, Closed Loop Stepper Motors (Step-Servo motors). We provide our customers with a wide selection of step motors with a range of: sizes, phases, and step angles as well as Custom Components & Custom Motors - Shaft, Lead Wires & Cables, Encoders, Pulley & Gear, Brake, IP Ratings, etc.

MOONS' stepper motors and motion control products are widely applied in many innovative applications, including: 3D Printers, extruders, stage lighting, CNC machines, analytical and medical instruments, packaging machinery, precision telescope positioning systems, laser cutters, Security Camera, engravers, image scanners, textile equipment, embroidery machine and robotics etc.
