The 57HM76-2804 is a NEMA 23 stepper motor with a round-type design, offering a compact and space-efficient solution for various applications. It provides a holding torque of 18 kg-cm, ensuring precise and reliable motion control. With its NEMA 23 standard size, it is well-suited for industrial automation, CNC machines, and robotics. The round-type design allows for easy installation and integration in different setups. This stepper motor delivers versatility and efficiency for tasks that demand accurate positioning and smooth operation in a compact form factor.

The stepper motors move in precisely repeatable steps, hence they are the motors of choice for the machines requiring precise position control.

The motor’s position can be commanded to move or hold in one position with the help of Stepper Motor Drivers. The Stepper motor provides excellent response to starting, stopping, and reversing pulses from the stepper motor driver.

NEMA Stepper Motors are very useful in various applications, especially which demands low speed with high precision. Many machines such as 3D Printers, CNC Router and Mills, Camera Platforms, XYZ Plotters, etc.

It is a brushless DC motor, so the life of this motor is dependent upon the life of the bearings. The position control is achieved by a simple Open Loop control mechanism so it doesn’t require complex electronic control circuitry.

The motor’s shaft has been machined for good grip with a pulley, drive gear, etc. and especially avoiding stall or slip.

We are engaged in supplying and wholesaling a quality approved collection of Stepper Motors which are highly acknowledged and accepted for long service life and high reliability. To explore more of them click below,
