Applied Motion Products HT34-489D Stepper Motor

The HT34-489D from Applied Motion Products is a high-torque two-phase stepper motor in the HT34 family built on a NEMA 34 frame with a 1.8° step angle. It delivers 1100 oz-in of holding torque at 5.1 A per phase, with coil resistance of 1.7 Ω and inductance of 10.5 mH per phase, and rotor inertia of 17.5 oz-in², making it well suited to smooth, repeatable micro-stepping at modest speeds. The motor measures 4.63 inches long (117.6 mm) and features a 0.5-inch (12.7 mm) shaft diameter; lead wires are included with the unit. This motor is commonly used in automation, CNC machinery, robotics, and packaging equipment where reliable high-torque shaft drive is required for precise positioning and load handling.
