HIGHTORQUE HYBRID STEPPER MOTORS DSMH

The hybrid stepper motors of Geeplus' DSMH series are high-torque stepping motors with 1.8 degree full step angle motors for microstepping mode; due to optimized rotor form and new square lamination geometry, they also have a very good efficiency. The DSMH stepper motor series comprises 7 flange sizes from 20mm to 110mm, each with several overall lengths. Audible noise generation has been minimized. These DSMH stepping motors are well suited for microstep operation.

 

The most important features of the DSMH Hightorque stepper motors are:

  • high speed: The high torque hybrid stepper motors of the DSMH series enable high acceleration. By the choice of winding, high operating speeds can be achieved compared to conventional stepping motors (typically 30 to 50% higher)
  • high torque: typically over 40% more torque than conventional stepper motors of the same size
  • available in several flange sizes: Nema 8 (20mm), Nema 11 (28mm), Nema 14 (35mm), Nema 17 (42mm), Nema 23 (57mm), Nema 34 (86mm) and Nema 42 (110mm)
  • high efficiency: the thin lamination and small air gap of the DSMH stepper motor series reduce electromagnetic losses to a minimum
  • low noise and vibration: the square form and the high rigidity of the laminations plus the specially designed tooth geometry help the DSMH stepper motors to ensure minimum audible noise and vibration
  • large shaft and bearing system: the DSMH series stepping motors include a heavy-duty shaft and large bearings assembly to allow for large side loads and axial forces
  • winding connections: Most stepping motors of the DSMH family have 8 connections. This enables the 2 phase windings to be connected in any desired circuit in serial or parallel or in unipolar or bipolar arrangement
  • three-phase version on request

HYBRID STEPPER MOTORS CT

The CT series hybrid stepper motors combine innovative cooling technology, a magnet design for high torque, robust bearings and high dielectric strength. These features ensure high torque output for heavy mechanical loads and enable use with all drives.

The outstanding performance is just one part of the CT Series' success story. The CE-certified motors are available in the common flange sizes (Nema17 (42mm), Nema23 (57mm) and Nema34 (86mm)) and in different lengths, with different windings and shafts.

 

The most important features of CT hybrid step motors are:

  • high-performance magnet design: large rotor diameter, small air gap and high-energy magnets as well as computer-controlled winding guarantee maximum torque at minimum volume
  • housing designed for cooling: Aluminium jacket and aluminium end pieces dissipate the heat of the motor very quickly. In this way, higher current and torque ratings can be achieved, especially when the motor is flanged. CT motors generate the same torque at lower temperatures and therefore offer a longer life
  • large bearing system: the CT series stepping motors have large bearings, therefore they allow large radial and axial forces
  • high dielectric strength: Low susceptibility to faults, as there are no connections or gaps thanks to the stator enclosed by a moulded insulating insert. Higher reliability and voltage ratings. CT series motors can be used with all standard and high voltage/high power drives
  • optional: digital incremental AquadB encoder
