5-Phase Stepper Motor Driver
The Autonics A3K-S545 is a 5-phase stepper motor driver supplied new in a single-unit box. It provides a basic step angle of 0.72° in full-step mode and 0.36° in half-step mode for precise positioning control. The driver delivers a maximum holding torque of 2.4 kgf·cm with a rated current of 0.75 A per phase. Winding resistance is specified at 2.2 Ω and rotor moment of inertia at 68 g·cm².
Suited for precision motion control
This driver suits engineers and technicians building or maintaining equipment that requires fine angular resolution from a 5-phase stepping system. The IP30 protection structure fits clean indoor environments such as laboratories or enclosed cabinets. It is not intended for applications needing higher torque output, different phase counts, or ingress protection against dust and water beyond the IP30 rating.
Pentagon wire connection
The winding uses a Pentagon connection topology, which dictates the wiring sequence and drive sequence compatibility for the 5-phase motor. Verify that your controller and motor wiring match this configuration before installation. The 3-year parts and 1-year labor coverage from the manufacturer applies to the unit.

Questions about this item
What step angles does the 5-phase driver support in full and half-step modes?
The driver supports a basic step angle of 0.72° in full-step mode and 0.36° in half-step mode.
What is the protection rating and physical mounting requirement for the IP30-rated driver?
The unit has an IP30 protection structure and requires a standard DIN rail or panel mount inside a suitable enclosure.
How do you wire the motor windings to the Pentagon connection terminals?
Connect the five motor leads to the corresponding Pentagon terminals matching the winding sequence; the common error is crossing adjacent phase wires.
