  • Speed: 2/8 poles, for translation use, two windings; 400V Υ or Δ, 50Hz.
Protection

IP55 protection providing good sealing against projected liquid and dust in an industrial environment.

Operating as a Variable Speed Motor

Fitted with thermal probes in winding (obligatory).

Finish: Aluminium housing

Routine test, no load test, dielectric test, control of the resistance and direction of rotation.
Protection of the flange and shaft end against atmospheric corrosion.
Individual anti-shock packaging.

Brake Motor Mains Supply

 Standard construction according to IEC 38:

 230/400V +10% -10% at 50Hz

» It is suitable for the following mains supply:
 220/380V +5 % –5 % at 50Hz
 240/415V +5% –5% at 50Hz
 400VΔ +10% –10% at 50Hz.

 Design suitable for Υ/Δ starting.

 The brake mains supply is integral and the brake motor connects as a standard motor. If it is separate: the alternating (AC) supply is exterior to the motor.

Options

 Choice of inertia (HA 71 to 100), brake torques
 Manual brake release
 Drip cover; 2nd shaft end; thermal probes
 Reduced response time; connector
 Encoders and/or forced ventilation.
