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. Signaler une autre image Vous avez trouvé des images choquantes. They have multiple coils that are organized in groups called phases. By energizing each phase in sequence, the motor will rotate, one step at a time.
Five geared type stepper motor solutions, encoder and brake options and various motor windings are offered.

A stepper motor is a brushless, synchronous electric motor that converts digital pulses into mechanical shaft rotations. Each rotation of a stepper motor is divided into a set number of steps, sometimes as many as 2steps. The stepper motor must be sent a separate pulse for each step.
These steppers are a great way to get things moving, especially when positioning and repeatability is a concern.
This is a simple, but very powerful stepper motor with a 4-wire cable attached. DC motors are analog motors , we can only send power signals (two wire) to the motor to drive them. Unlike DC motors , stepper motors do not have brushes nor commutator – they have several independent coils, which are commutated with exterior electronics ( drivers). Rotating the rotor is done by commutating coils step by step, . Also known as step motors or stepping motors , these brushless DC motors offer quick, precise positioning and exceptional holding torque.

The rotor of a stepper moves in a series of discrete steps. Hybrid stepper motors provide excellent performance in areas of torque, spee and step resolution.
Typically, step angles for a hybrid stepper motor range from 2to 4steps per revolution. This type of motor provides a combination of the best features available on both the PM and VR types of stepper motors. Web motors are available for online purchase. Customize with single or double shaft or add encoder option. Perfect for simple, one-off, projects.
They also have encoderless stall detection for reliable control. To support various system requirements, the drives feature options, . They are available with a wide variety of modular servo components like encoders, zero backlash gearheads, .
The shaft of a stepper , mounted with a series of magnets, is controlled by a series of electromagnetic coils that are charged positively and negatively in a specific sequence, precisely moving it . Full, half or microstepping operation options available. Delivery in days or less is available for many products. Although feedback is not usually require stepper motors are compatible with feedback signals, either analog or digital.
Error is noncumulative as long as pulse-to-step integrity is maintained by the step motor. A stream of pulses can be counted into stepper motors , and the final . Our stepping motors are especially designed for engineers and experts, and renowned for wide selection, high quality, high performance and unique features.
