Our take on the AMCI Motion Control SM34-850 NEMA 34 Stepper Motor

The AMCI SM34-850 is a NEMA 34 stepper motor rated at 906 oz-in of holding torque at 4 A, in a 3.8-inch-long body weighing about 6.3 lb. It has a 0.50-inch shaft with a double flat for secure coupling. AMCI matches it to its own stepper drives and controllers, so it suits builders of precise positioning and indexing systems already in the AMCI ecosystem. Against generic NEMA 34 motors, its value is the factory matching rather than standout torque for its size.

Questions and answers

What does 906 oz-in of holding torque mean in practice?
It is the torque the motor holds when stopped with current applied. It sets how much load the motor can resist before it slips, and it is the figure to compare against other NEMA 34 motors.
Can I run it with a non-AMCI driver?
It is a standard 4 A stepper, so a compatible stepper driver can run it. AMCI tunes it to its own drives and controllers, so matching those gives the intended performance.
What shaft does it have?
A 0.50-inch shaft with a double flat, which takes a coupling or pulley with a matching bore and set screw.
How big is it and how much does it weigh?
The body is 3.8 inches (97 mm) long and the motor weighs about 6.3 lb. Check clearance for the shaft and connector behind the mounting face.
Does it have an encoder or closed-loop feedback?
No encoder is listed. For closed-loop control you would add an encoder or choose a servo or closed-loop stepper instead.
Where is the AMCI Motion Control SM34-850 NEMA 34 Stepper Motor cheapest?
At PLG Automation, for $288.00, as of our latest check.
