RS PRO Hybrid Stepper Motor, 3.8 (Unipolar) nm, 4.8 (Parallel) nm, 4.8 (Series) nm Torque, 2.54 V, 4.76 V, 6.6 V, 1.8°,

Hybrid stepper motors from RS PRO are high performance DC motors, perfect for applications requiring precise movement or rotation in steps. They combine characteristics from both VR (variable reluctance) stepper motors and PM (permanent magnet) stepper motors, offering a versatile motor suitable for a range of applications. With RS PRO hybrid stepper motors, high torque can be achieved even with low speeds.

Depending on the type of application required, this range of stepper motors can achieve various speeds, torque and power outputs. This can be achieved by wiring them as either series, parallel or unipolar, offering a highly versatile and reliable stepper motor.

A stepper motor is a type of DC motor with a shaft that turns in precise steps by dividing full rotations via multiple coils that are organised in phases. Stepper motors are ideal for applications requiring discrete and precise torque or movement. These motors offer a variety of driver modes including wave drive, full step, half step and micro-step and can be operated via stepper controllers. Stepper motors are commonly used in applications such as:

CNC machines
Medical scanners
Printers
Disc drives
Digital cameras

This stepper motor features a 1.8° step angle, equivalent to 200 steps per revolution.

The length of the shaft is 28.9mm.

The max radial force for this model is 220 N (20 MM from front flange).

The max axial force for this model is 60 N.

Unipolar stepper motors operate with a single winding with a center tap per phase. Each section of the winding is switched on for each direction of the magnetic field. Unlike the unipolar stepper motor, the bipolar stepper motor has two leads per phase, neither of which are common.

Motors can be wired as either series or parallel, depending on the type of application that is required. A series wired motor generally provides increased stall torque that decreases as more velocity is applied. Motors wired in parallel tend to maintain a constant torque at a higher velocity, however, this is usually lower than series.

The winding configuration or a stepper motor plays a vital role in providing the required operating speed, torque and power outlet.
