Rotor

- rare earth permanent magnets ( NdFeB )
Insulation

- winding, class H; Motor Class F
Winding
Standard

- 1500rpm
- 3000rpm
- winding for 230VAC for 400VAC mains drives
On demand

- other combinations of voltage and speed possible..
Isolation

- class H winding
- class F motor
- Insulation suitable for 400VAC
Thermal protection sensors
Standard

- by means of PTC, only for 400V sizes
Options

- No other options
Cooling system

 

- natural air ( IC0041 )
Standard protection
  

- IP65 (shaft side excluded). IP65 protection on the shaft side must be requested and is considered effective only in the presence of an oil bath coupling or with the presence of lubricant.
Ballbearings

- ball bearings with double shield lubricated for life
Balancing

- Grade "R"
Axis/flange concentricity and perpendicularity

- grade "N" (normal) - according IEC 72 - DIN0530
Shaft output

- with key, with coaxial threaded hole
Brake

- optional. Permanent magnet parking brake, 24VDC power supply with determined polarity.Brake engaged in the absence of power. Braking torque greater than the motor Tn
- Brake not suitable for dynamic stops. It can tolerate a limited number of emergency braking operations
- Due to the power dissipated by the brake it is recommended to derate the motor stall torque by 5%..
