The Electro Spindle is available in two models, the HT and the HM, all capable of variable speeds ranging from 12,000 rpm to 24,000 rpm

HT Spindle Motor
The HT Spindle motor can accept light plunge cutting, inducing axial loads, but is most suitable for those applications mainly involving radial loads.
HM Spindle Motors
The HM spindle motor features a double angular contact thrust bearing at the work end or ceramic bearings, with a single deep groove support bearing at the opposite end (or, again, a double angular contact thrust bearing). This motor is designed for those applications requiring heavy plunge cutting, inducing high axial loads, on regular basis.
nefits include:
Competitive prices;

• High Torque design;
• Superior quality copper rotor;
• Very low noise levels with a superior cooling fan design;
• Minimum working temperatures providing extended bearing life;
• Dynamically balanced rotor to ISO tolerances ;
  * Low load loss and absorbed current for increased energy savings;
  
  Shafts available include:
• Type L - Cylindrical shaft without a key, but with a locking nut;
• Type P - Inside collect taper with locknut;
• Type T - cylindrical shaft with a key and a locking nut.
• riable speed frequency drives to increase or decrease the motor speed.
