About the Product

Stepper Motor NEMA 34 45kg-cm

Our Stepper Motor Nema 34 45kg-cm are great for position control. They can be found in desktop printers, plotters, 3d printers, CNC milling machines, and anything else requiring precise position control. These are a special segment of brushless motors. They are purposely built for high-holding torque. This high-holding torque gives the user the ability to incrementally “step” to the next position. This results in a simple positioning system that doesn’t require an encoder. This makes stepper motor controllers very simple to build and use.

This is a Bipolar stepper

Wiring Diagram

Mechanical Dimension

The following diagram shows the stepper motor dimensions in mm.


  • Low cost for control achieved
  • High torque at startup and low speeds
  • Ruggedness
  • Simplicity of construction
  • Can operate in an open loop control system
  • Low maintenance
  • Less likely to stall or slip
  • Will work in any environment
  • Can be used in robotics on a wide scale.
  • High reliability
  • The rotation angle of the motor is proportional to the input pulse.
  • The motor has full torque at standstill (if the windings are energized)
  • Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3 – 5% of a step and this error is non-cumulative from one step to the next.
  • Excellent response to starting/stopping/reversing.
  • Very reliable since there are no contact brushes in the motor. Therefore the life of the motor is simply dependant on the life of the bearing.
  • The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
  • It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
  • A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.


  • Require a dedicated control circuit
  • Use more current than D.C. motors
  • Torque reduces at higher speeds
  • Resonances can occur if not properly controlled.
  • Not easy to operate at extremely high speeds.
