NEMA23 PR57HS112-4204 31kg-cm Stepper Motor-D Type Shaft
The NEMA23 PR57HS112-4204 is a high-torque stepper motor delivering 31 kilogram-centimeters of holding torque, engineered for precision motion control applications requiring reliable positioning accuracy and consistent performance. Professional automation engineers, CNC machine builders, and robotics developers rely on this motor for its exceptional torque-to-size ratio and D-type shaft configuration that ensures secure mechanical coupling without slippage. This stepper motor solves critical challenges in applications demanding precise angular positioning, repeatable motion cycles, and high holding force without external braking mechanisms.
Product Overview
The NEMA23 PR57HS112-4204 operates on the electromagnetic principle of stepper motor technology, where energized coils create rotating magnetic fields that advance the rotor in discrete angular increments. The motor features a 57mm frame size (NEMA23 standard) with a D-type shaft, providing superior torque transmission compared to round shafts through its flat-faced design that prevents rotational slippage under load. This model stands out in its class due to its 31kg-cm holding torque specification, making it suitable for applications requiring sustained positional accuracy without continuous power consumption, and its robust construction ensures longevity in industrial environments with temperature variations and mechanical stress.
The PR57HS112-4204 integrates advanced magnetic circuit design with precision-wound stator coils to deliver consistent torque across variable speed ranges from low-speed high-torque operation to higher-speed applications. The D-type shaft configuration provides positive mechanical engagement with standard couplings and pulleys, eliminating the risk of mechanical slippage that can occur with round shafts under dynamic loading conditions. The motor's construction includes precision ball bearings, laminated stator cores for reduced eddy current losses, and optimized winding geometry that balances torque output with thermal efficiency, making it an ideal choice for demanding industrial automation, laboratory equipment, and custom machinery applications.

How to Use
Installation of the NEMA23 PR57HS112-4204 begins with mechanical mounting using the four M5 threaded holes on the 57mm mounting face, ensuring the motor is secured to a rigid structure with appropriate vibration isolation if needed. The D-type shaft should be coupled to your driven load using a standard flexible coupling or direct mechanical connection, ensuring shaft alignment within 0.1mm runout to prevent premature bearing wear. Electrical connection requires a stepper motor driver circuit capable of delivering the appropriate current and voltage to the motor coils, typically operating at 12V to 48V DC with current ratings between 2.5A to 4.0A per phase depending on your specific performance requirements.
Configure your stepper driver for 1.8-degree step angle operation (200 steps per revolution), and implement microstepping if your application requires smoother motion or reduced vibration. Start with lower acceleration profiles and gradually increase speed to allow the motor to develop full torque without stalling, particularly important when driving loads with significant inertia. Monitor motor temperature during operation, as stepper motors generate heat proportional to current and duty cycle; ensure adequate cooling or thermal management if running continuously at maximum current. The holding torque of 31kg-cm means the motor will maintain position without power, but always include mechanical brakes or locking mechanisms for safety-critical vertical load applications.
Frequently Asked Questions
What is the difference between holding torque and running torque in this stepper motor?
Holding torque (31kg-cm) is the maximum load the motor can resist when stationary with coils energized, preventing rotation from external forces. Running torque varies with speed and current, typically reaching 80-90 percent of holding torque at low speeds and decreasing as speed increases due to back-EMF effects. This motor maintains excellent holding torque across its operating range, making it ideal for applications requiring sustained positional accuracy without continuous power draw.
Can I use this NEMA23 motor with microstepping drivers?
Yes, the PR57HS112-4204 is fully compatible with microstepping drivers supporting 1/2, 1/4, 1/8, and 1/16 step divisions. Microstepping reduces vibration and noise by distributing current across multiple coil phases, enabling smoother motion particularly beneficial in precision applications. Your driver circuit must support the motor's bipolar configuration and provide appropriate current limiting for your chosen microstepping resolution.
What is the maximum speed this stepper motor can achieve?
The PR57HS112-4204 can operate up to 3000-4000 RPM depending on driver voltage, current, and load inertia, though practical speed is typically limited by load torque requirements. At higher speeds, available torque decreases due to back-EMF, so applications requiring full 31kg-cm torque should operate below 1000 RPM. Your specific maximum speed depends on acceleration profile, load characteristics, and driver capabilities.
Is the D-type shaft better than a round shaft for my application?
The D-type shaft provides superior mechanical engagement compared to round shafts, as the flat surface prevents rotational slippage under load without requiring set screws that can damage shafts. D-shafts are ideal for high-torque applications, precision machinery, and systems where mechanical reliability is critical. Standard couplings and pulleys designed for D-shafts ensure positive drive without backlash.
