Product Details

STMPW57

The STMPW57M series integrated waterproof wide-temperature stepper servo motor is a waterproof wide-temperature stepper servo product independently developed by NiMotion. Based on the excellent closed-loop control system and the highly integrated integrated design concept, this product integrates the stepper motor, brake, encoder, driver and digital IO into one, supporting CANopen and RS485 communication bus control. This series has an integrated motor protection level of IP65, which can work stably in the ambient temperature range of -40 ℃ to +75 ℃, and has the characteristics of compact structure, simple wiring and strong environmental adaptability.


Product Features

Highly integrated design

Integrates Stepper motors, brakes, encoders, drives and digital IO 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 encoder, multi-turn absolute counting, automatic storage after power failure 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 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 VDC, 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 Solar Photovoltaic Tracking Bracket Equipment

The STMPW57 series motor is an IP65-rated stepper motor that supports wide-temperature operation, specifically designed for outdoor or harsh industrial environments with extreme temperatures (-40°C to +75°C), high dust, high humidity, and strong chemical corrosion. Featuring a built-in driver, controller, and encoder, it offers a compact design that eliminates the need for external driver components while delivering high torque. It converts rotary motion into linear displacement of push rods or worktables.
