Our take on the SureStep STP-MTRH-34127 NEMA 34 DC Brushless Stepper Motor

The SureStep STP-MTRH-34127 is a NEMA 34 brushless stepper motor built for high-torque positioning and motion control. It delivers 1288 oz-in of holding torque at 6.3A per phase with a 1.8° step angle, giving accurate incremental movement in industrial automation and CNC setups. Against smaller NEMA 23 motors it trades compactness for far more torque, and against closed-loop servo systems it is simpler and cheaper to drive but lacks feedback. It suits machine builders who need repeatable rotary motion and can supply a matching high-current driver.

Pros
  • High 1288 oz-in holding torque for its frame size
  • Standard NEMA 34 mounting footprint
  • 1.8° step angle gives fine incremental control
  • Simple open-loop stepper design, no encoder wiring
  • DC brushless construction
Cons
  • Draws 6.3A per phase, so it needs a capable driver and supply
  • Open-loop control can lose steps under overload
  • Heavy and bulky compared with NEMA 23 motors
  • No position feedback, unlike a closed-loop servo

About the SureStep STP-MTRH-34127 NEMA 34 DC Brushless Stepper Motor

The SureStep STP-MTRH-34127 is a NEMA 34 DC brushless stepper motor for positioning and motion control. It is a two-phase bipolar motor with a 1.8° step angle, or 200 steps per revolution. Holding torque is 1288 oz-in at 6.3 A per phase.

The motor has a single 1/2-inch shaft for direct coupling to mechanical loads and drive assemblies. It has an IP40 rating, so it is meant to be installed inside control panels or protected enclosures where exposure to contaminants is limited.

A 1-foot cable with a 4-position male connector is pre-attached. An STP-EXTH-xxx extension cable is required to connect it to a system. The motor is intended for industrial positioning, indexing and automated motion control.

Questions and answers

What driver does this motor need?
It needs a bipolar stepper driver rated for at least 6.3A per phase and a DC supply matched to that current. Size the driver above the motor's rated current so it does not run at its limit.
Is this a servo or a stepper motor?
It is a brushless stepper motor, not a servo. It moves in fixed 1.8° steps and runs open-loop, so it has no encoder feedback.
How much holding torque does it produce?
1288 oz-in at 6.3A per phase. That is high for a NEMA 34 frame and suits loads that smaller motors would stall on.
Will it bolt up where a NEMA 23 motor was?
No. NEMA 34 has a larger face and bolt pattern than NEMA 23, so the mount and coupling need to match the bigger frame.
What is the step angle and resolution?
The step angle is 1.8°, which is 200 full steps per revolution. Microstepping drivers can divide that further for smoother motion.
Where is the SureStep STP-MTRH-34127 NEMA 34 DC Brushless Stepper Motor cheapest?
