Phidgets NEMA-23 Bipolar Stepper Motor 1.8deg, 2.8A, 77:1

• Phidgets NEMA-23 Bipolar Stepper Motor 1.8deg, 2.8A, 77:1
• 240 kg-cm torque rating
• 1.8 degree step angle (0.023 degrees after gearbox)
• 77:1 planetary gearbox
• Rated for 2.8A of current
• Connects to a Phidgets stepper controller

The Phidgets NEMA-23 Bipolar Stepper Motor 1.8deg, 2.8A, 77:1 features an integrated 77:1 planetary gearbox, delivering precise motion with a step angle of 1.8° at the motor shaft, which translates to approximately 0.023° at the output of the gearbox. The motor includes an exposed rear shaft, allowing for easy integration of an encoder or shaft coupler. Designed for high-performance applications, it offers a holding torque of 240 kg·cm and can produce up to 960 kg·cm of torque at 2.8 A, though the gearbox is rated for continuous torque of 240 kg·cm. Users should calculate exact step angles by dividing the motor’s 1.8° step angle by the gearbox reduction ratio for accurate motion planning.

This stepper motor operates at 24 V DC and must be used with a constant current or chopper drive controller, such as a Phidgets stepper controller, to avoid damage and maintain warranty coverage. Its robust NEMA-23 design, combined with the planetary gearbox, provides reliable performance for robotics, CNC, and automation projects. Key features include a 240 kg·cm torque rating, precise motion control with 0.023° step increments after gearing, and compatibility with Phidgets stepper controllers, making it an ideal choice for demanding precision applications.
