Infranor Easy Brushless Servo Drives Review: Specs, Price and Applications
Infranor Easy is a low-voltage servo-drive family for three-phase rotary and linear motors. The supplied range lists a 24–60 VDC bus, 5–35 A RMS continuous-current classes and housed or PCB daughter-board forms. Feedback choices include resolver and incremental encoder arrangements.
Quick Verdict
Useful for a low-voltage axis where the selected current class and feedback fit the motor. The housed and board-level forms have different installation and thermal responsibilities.

Design and Engineering Assessment
An RMS current rating should be compared using the same current convention and operating conditions as the motor specification. Peak and RMS values are not directly interchangeable labels.
A daughter-board implementation transfers cooling and external connection design to the OEM assembly. That scope should be included when comparing it with the housed version.
Current, Voltage and Duty Cycle
A servo drive’s continuous current, peak current and supply envelope describe different constraints. Peak capability supports acceleration for a limited interval; continuous capability determines whether a repeated motion cycle can run without excessive temperature. The useful operating point also depends on the motor winding and back EMF. A nominal wattage therefore serves as an initial selection aid rather than a complete sizing result.
Deceleration can return energy to the DC bus. A machine with a large moving mass or repeated rapid stops needs a defined path for that energy, whether through a shared bus, an appropriate braking arrangement or a regenerative supply. The drive, supply and protection devices must be considered together so that a normal stop does not become an overvoltage trip.
Feedback and Command Architecture
Confirm the exact feedback format, commutation method and electrical interface before connecting a motor. Incremental, absolute and Hall feedback have different purposes and wiring requirements. The machine controller’s command mode must also agree with the drive’s operating mode; a torque-controlled amplifier relies on a different supervisory arrangement from a drive that closes its own position loop.
Motor power and feedback cables should be routed and terminated according to the selected equipment’s electrical design. Connector fit alone does not establish a valid pinout. For an existing machine, preserving the approved motor parameters, direction conventions and fault handling is more reliable than assuming that two similarly rated drives are interchangeable.
Tuning and System Acceptance
Tune with the actual mechanism and representative load. Coupling stiffness, gearbox compliance and structural resonances can limit the useful bandwidth even when the electronics offer fast control updates. Start from stable current and velocity behavior, then assess position tracking and settling against the machine’s acceptance criteria. Faster loop settings are useful only when the mechanics and feedback support them.
Fault recovery should be part of acceptance testing. Check the response to following error, feedback loss, network interruption and a commanded stop under the intended machine design. A protection function in a drive does not by itself establish the safety performance of a complete machine; that depends on the selected functions, wiring and system architecture.
Applications and Selection
Low-voltage rotary and linear servo systems.
For Infranor Easy Brushless Servo Drives, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Price: Request a quote for the exact configuration. Compare the product, compatible control equipment, required mechanical parts, cabling and commissioning as one installed system. A component price alone does not represent the cost of a working automation axis.
Evaluate an alternative against the same duty and acceptance criteria. Match the continuous operating requirement first, then compare transient capability, feedback, mechanical fit and support. This avoids choosing between superficially similar products whose ratings describe different operating conditions.
