Crouzet - BLDC planetary geared motor with integrated SMi21 drive

  • 12→48 V dc, 52→81 mmØ, 25→120 Nm, 9→756 rpm
  • Speed, torque & postion control
  • Reduce control panel space & cabling
  • Long life (>20,000 hours)
  • IP65 as standard

Product description

The SMi21 integrated drive is ideal for applications where speed, torque & positional control is required.

The motor also incorporates a high resolution 4096ppr incremental encoder ideal for precise positioning applications.

Motion programming, configuring & set-up performed through the dedicated user friendly DCmind-soft PC software. The program can be controlled via basic switches or by external PLC.

The long lifetime of the brushless motor (>20,000 hours with rated load) means it is ideal for continuous or long duty applications.

Having the drive integrated into the motor can also save control panel space, reduce cabling and save set-up time.

3 motor sizes available with the same diameter (57mm x 57mm), with increasing motor lengths for more power/torque.

Planetary & worm gearbox options available for reducing the speed & increasing the output torque.

The motors are rated to IP65 dust/water protection class as standard.

Options for adapation to the standard motor include adding a holding brake, special output shaft, special connectors, upgraded IP protection & special firmware developed according to your specific application requirements.


* Product datasheets & 3D drawing for standard IP65 cable version attached as an example. Further information for braked version available upon request.

Full documentation & user manuals also available upon request.
