2-Phase Closed-Loop Motors
A system consists of MOTOR, DRIVER and ENCODER EXTENSION CABLE.
The output stage and the motor are separated, which allows a protected and well cooled installation.
These closed loop drives have the special feature that the position of the motor shaft is measured by an encoder and fed back to the motor driver. The driver can thus check whether the motor has executed the desired movement and adjusts during the movement. This avoids step losses and provides a high level of safety. Further advantages are a higher torque and speed and the possibility to accelerate faster.
We supply only original goods from LEADSHINE, ex stock Germany.
System description
The motors of this system have 3 coils instead of the usual 2, thus they provide a higher torque. The control is done by a driver, which is optimized for these 3-phase motors. Only 3 wires are necessary for the connection between driver and motor. The motors have built-in axis encoders that report the position to the driver. This allows the driver to operate the motor in a closed loop, hence the name "closed loop stepper motor". The systems are ready for operation immediately after connection, no tuning is necessary.These closed-loop drives have the special feature that the position of the motor shaft is measured by an encoder and reported back to the motor driver. The driver can thus check whether the motor has also executed the desired movement and readjusts during the movement. This avoids step losses and provides a high level of safety. Further advantages are a higher torque and speed and the possibility to accelerate faster.

Closed loop drives for automation
What are closed-loop stepper motors?
Closed-loop stepper motors combine the advantages of stepper and servo motor technology. They are smoother running and have lower resonance than stepper motors, offer position feedback and control, short settling and decay times, and no longer exhibit step loss.
They are an alternative to stepper motors when energy efficiency, smooth running and high load tolerance are required. Compared to servo motors, they have advantages in terms of high torque at low speeds, short settling times, correct positioning without hunting, and a lower price with often smaller size.
When are closed-loop stepper motors a good alternative?
- When high torque is required at speeds up to 1000 rpm and a compact, low-cost solution is needed that does not require a gearbox.
- When simple and fast commissioning without complex tuning is required.
- When a low-cost drive is required as an alternative to servo motors.
- When a load must be held in position at standstill (e.g. Z-axis of a milling machine).
- When the typical hunting behavior of servo motors leads to tracking errors that are intolerable for the application. Servo motors overrun their position in the event of sudden load changes and must then be corrected.

Advantages of Rocketronics
About Rocketronics
Rocketronics was founded in 1999 as a family business by Louis Schreyer. As an engineer for microelectronics, I design hardware and also develop the software for it. We manufacture our products in-house on our own machines, and this for over 20 years now - made in Germany. In addition to the development and production, the testing of the products is also carried out here. We also manufacture the prototype construction and the test fixtures ourselves. We use lathes and milling machines for this, but we also use our 3D printers a lot. The CNC milling machines we build ourselves produce many small parts, e.g. for the housings of our controllers.In addition to manufacturing controllers, we also trade in the necessary components. As a dealer we have a large stock of components for machine building and automation, which we offer in this store. Our suppliers are the original manufacturers, with us you buy tested branded goods.
We also consult you when it comes to choosing the right components. We have a lot of experience in building and operating CNC milling machines and lathes. We can help you if you have questions, be it about the control system, the choice of drives or in general about the construction of CNC milling machines and the conversion of lathes.
Our online store shows you all items available for immediate delivery, and allows you to shop securely with many payment methods and fast shipping. Data traffic is of course encrypted, payment is processed and secured by reputable service providers, and we offer a 30-day return policy.
