Brushless DC Servo Motors

MotorsOverviewA servo motor can be any type of motor coupled to a sensor for position feedback, usually an incremental encoder. A sophisticated controller (or drive) is required that can monitor position and speed against target values and adjust accordingly. This...

Integrated Stepper Motors

MotorsOverviewIntegrated stepper motors have the driver mounted directly on the motor for ease of integration, reduced wiring complexity and compactness. Our new series of integrated stepper motor drivers – SMD-mini – is designed for small and medium size stepper...

Closed Loop Stepper Motors

MotorsOverviewClosed loop stepper motors offer the low speed torque of a stepper with the accuracy of a servo motor when used with a suitable drive. They consist of a conventional stepper motor with an attached precision encoder for position feedback, eliminating...

Open Loop Stepper Motors

Overview

Stepper motors (sometimes called step motors or stepping motors) provide low cost motion control without the need for feedback devices such as encoders. However, if greater accuracy or step-loss detection is required, it is possible to use encoders with stepper motors and ORLIN also has a range of preconfigured closed loop stepper motors available.

Typical number of steps per revolution is 200, but this may be increased by microstepping for greater positioning resolution and operating smoothness. With the appropriate drive, microstepping can increase the resolution up to 51200 steps/rev.

ORLIN Technologies offers a range of stepper motors in various sizes. We also offer matching drives and programmable controllers for all models and integrated drives for most. An integrated motor is one where the drive is built into the unit which reduces wiring, takes up less space and eases installation.
