DcStep closes the gap between fully featured closed-loop Stepper Motor Drives and cost-efficient Open-Loop Systems.
While most-open loop stepper drives will lose steps in an overload situation, dcStep™ drives will reduce speed in order to overcome resistance. As a result, dcStep uniquely maintains position counter integrity.
With dcStep a stepper motor will act similarly to a DC motor in terms of energy efficiency. dcStep also allows for auto ramping and turning the motor as fast as possible in actual load situations.
DcStep addresses stepper motor drives' needs to maintain positional self-awareness and step count without costly feedback circuitry.
Without feedback circuits, operating margins must be restricted, so that motor torque and velocity are maintained within acceptable levels.
The dcStep technology provides extra torque to match sudden increases increases in load resistance while preserving step count. This significantly reduces previously required stepper motor control system safety margins to increase system or reduce motor size.
