In the past, a traditional stepper motor system has typically been based on a central controller unit located remote from the stepper motor itself. This configuration however has the negative effect that installation costs are a major part of the total expense of building machinery.
The basic idea of the QuickStep stepper motors is to minimize these costs but also to make a component that is much better protected against electrical noise which can be a typical problem when using long cables between the controller and the stepper motor.
The stepper motor, encoder and electronics are specially developed by JVL so that together they form a closed unit in which the power driver and controller are mounted inside the stepper motor in a closed section.
The advantages of this solution are:
* De-central intelligence.
* Simple installation. No cables between stepper motor and driver.
* EMC safe. Switching noise remains within the stepper motor.
* Compact. Does not take space in cabinet.
* 12-48VDC power.
* Low-cost alternative to separate stepper motor or servo motor and driver.
Interface possibilities to the QuickStep motor:
* From PC/PLC with serial commands via RS232/RS485.
* Pulse/direction input. Encoder output.
* Option for ‚µPLC built-in with graphical programming.
* CANopen, DeviceNet
* 8 I/O, 5-28VDC that can be configured to Inputs, Outputs or analogue inputs
* Future option for Profibus DP, Bluetooth and Zigbee wireless
QuickStep is a new series of stepper motors from JVL which can be delivered with a large selection of functions and in a wide variety of combinations. The base is a hightorque NEMA23 stepper motor with a housing so that IP55 or larger protection can be achieved. One or more circuit cards and different connectors can be mounted in the housing to adapt the stepper motor to a given task.
Backlash free and planetary gears in ratios of 3, 5, 10, 20, 100 can be delivered from stock.
