Applied Motion STAC6 Hazardous-Location Stepper Drive Review: Specs, Price and Applications
The STAC6 offering described by Electromate is a mains-powered stepper drive for specified hazardous-location configurations. Its listing includes a 94–135 VAC single-phase supply, up to 6 A per phase and microstepping up to 51,200 steps per revolution.
Quick Verdict
Worth evaluating where both stepper performance and the exact hazardous-location approval are required. The ordering code, installation conditions and applicable approval documentation must match the intended location.

Design and Engineering Assessment
A certification statement must be matched to the exact model, gas or area classification and installation conditions. An approved drive does not automatically make an enclosure, motor and complete machine suitable for the same location.
An optional encoder can support stall-related functions, but the selected drive configuration and control mode determine how that feedback is used. Large microstep counts should not be presented as a direct measurement of positioning accuracy.
Motor Matching and Resolution
A stepper drive must match the motor’s phase arrangement, winding connection and required current. The supply voltage influences current rise and available torque as speed increases. Select against the motor-and-drive speed curve and the machine’s complete duty rather than treating the motor’s holding torque as a running-torque guarantee.
Microstepping changes the number of commanded increments and can smooth motion. It does not turn each command increment into an equally accurate measured shaft movement. Load torque, friction and mechanism stiffness still influence position. Where an encoder option is available, establish exactly how the selected drive uses that feedback for detection or correction.
Control and Electrical Installation
The controller and drive must agree on command format, electronic gearing, direction and enable behavior. A high steps-per-revolution setting increases the pulse rate needed for a given shaft speed. Networked or stored-program modes introduce their own timing and supervision requirements, so they should be compared through the complete control architecture.
The electrical installation must provide the appropriate supply, protection, grounding and cable arrangement. Keep motor power wiring and sensitive command or feedback signals organized according to the selected equipment’s requirements. A drive protection feature does not replace the mechanical limits, stopping sequence and fault handling required by the machine.
Qualification and Service
Commission with the representative load, acceleration and highest intended speed. Evaluate warm operation over a realistic production cycle and define recovery after a jam or interrupted move. An unloaded demonstration can miss the conditions that cause missed steps, excessive heating or unstable motion in service.
Record the motor connection, current setting, resolution, control source and reference procedure. For a product with a location-specific approval, the full ordering code and permitted installation conditions are also part of the qualification record. The completed machine must meet its own requirements; approval of one component does not establish approval of the entire installation.
Applications and Selection
Stepper axes in installations that require the corresponding verified hazardous-location configuration.
For Applied Motion STAC6 Hazardous-Location Stepper Drive, 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.
