Integrated Closed-Loop-Stepperdrives from Just Motion Control
This is an integrated system with MOTOR, ENCODER and DRIVER in one unit.
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 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 JMC, ex stock Germany
System description
The motors of this system are 2-phase hybrid stepper motors which have an encoder with 1000 steps at the rear shaft end. The control is done by a driver, which is optimized for these 2-phase motors and is mounted directly on the motor. Cables for power supply and control signals must therefore be included for connection. The motors have built-in 1000-dash axis encoders that report the position to the driver. This enables the driver to operate the motor in a closed control loop, hence the name "closed-loop stepper motor".The systems are ready for operation immediately after connection, no tuning is necessary.

System components of the integrated motors
The motor system is integrated, motor, driver and encoder form one unit.
An RS-232 interface allows communication with a PC software from JMC, thus many parameters of the drive can be set.

Advantages of closed-loop drives
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 the optimal 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.

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.
