Product Details
The STMP42S series integrated waterproof stepper servo motor is a waterproof stepper servo product independently developed by NiMotion. Based on the highly integrated integrated development concept, this product integrates the stepper motor, encoder, servo drive, controller and digital I/O into one, adopts FOC (field-oriented control) and drive and control integration technology, supports EtherCAT, CANopen and RS485 bus control, and has the characteristics of compact structure and simple wiring. Stepper servo motors have the dual functions of servo motors and stepper motors, and the price is lower than that of servo motors, which can provide cost-effective solutions for applications that require the performance of servo motors.
Product Features
Highly integrated design
Integrates Stepper motors, encoders, servo drives, controllers and digital I/O into a single compact unit, so no external drive is required. Compared with conventional separated solutions it saves considerable installation space, needs less wiring, and makes commissioning and maintenance easier.
High Precision Encoder Feedback
Built-in 17-bit single-cycle absolute encoder, 17-bit multi-cycle absolute encoder provides real-time position and speed feedback for more accurate closed-loop control; multi-turn absolute counting and automatic position storage on power loss mean no re-homing is needed after power-up.
Multi-bus communication support
Supports EtherCAT, CANopen and RS485 communication, allowing quick connection to mainstream PLCs, motion controllers and host systems, with flexible networking and easy expansion.
Standard CiA 402 Sport Mode
Supports CiA 402 standard motion modes (PP, PV, HM, CSP, CSV, etc.) as well as position mode, velocity mode and torque mode, ensuring compatibility with mainstream fieldbus motion-control architectures and making replacement and commissioning easier.
Wide Voltage Input
Wide input voltage range of 16-52 (18~52), suitable for various power-supply environments and giving greater flexibility in system integration and retrofitting.
Complete diagnosis and protection
Comprehensive diagnostics and protection covering over-voltage, under-voltage, over-temperature, stall, overload, over-speed, over-travel and homing timeout, with current and historical alarm records for safer operation.
Application in Engraving Machine Equipment
The STMP42S series IP65-rated integrated motor upgrades small engraving machines from "vulnerable and interference-prone" to "dustproof, waterproof, and maintenance-free." It is particularly suitable for long-duration processing of stone, wood, or metal workpieces that require coolant in open environments (without protective covers). It ensures micron-level machining precision while significantly reducing downtime and maintenance caused by dust and liquid ingress.
IP65 Protection Rating – Waterproof and Dustproof
The product features excellent sealing performance, effectively preventing the ingress of external dust and water mist. With stronger adaptability to various working conditions, the motor delivers outstanding overall performance and higher reliability.
