Active parts (rotor and stator) of SIMOTICS M-1PH2 built-in asynchronous motors

SIMOTICS M-1PH2 built-in motors for turning machines are liquid-cooled squirrel-cage AC asynchronous motors. These built-in motors have been specially developed for variable-speed operation of main spindles on turning machines.

Характеристика



Typical speed/power graph for AC motors1)

The graph shows the typical relationship between motor speed and drive power for  SIMOTICS M-1PH2 motors for the following duty types in accordance with IEC 60034-1:

S1: Continuous duty

S6: Continuous duty with intermittent loading and a relative duty factor of 60 % (S6-60 %) or 40 % (S6-40 %) with a maximum duty cycle time of 10 minutes.

2) SINAMICS S120: Values taken from the speed/power graph when using an Active Line Module on a 400 V 3 AC supply system. If you are using a Smart Line Module, proceed in accordance with the 1PH2 Motors Configuration Manual.

2) SIMODRIVE 611: Values taken from the speed/power graph with regulated infeed. When using unregulated infeed modules, proceed in accordance with the 1PH2 Motors Configuration Manual.

Особенности


  • Compact design obtained by dispensing with mechanical components such as coupling, belt drive, gearbox and spindle encoder
  • High power density as a result of liquid cooling
  • The absence of drive transverse forces permits extremely high accuracy on work piece due to smooth, accurate spindle motion even at very low speeds
  • Extremely short ramp-up and braking times
  • Full rated torque is continuously available, even at standstill
  • Simple servicing by replacing complete motor spindles
  • Increased rigidity of the spindle drive, achieved by mounting the motor components between the main spindle bearings
  • C-axis compatibility with hollow-shaft measuring system mounted on the spindle
  • Low noise level due to absence of machine elements
  • Torque is transmitted to the spindle mechanically without play by means of a cylindrical stepped press fit. The rotor is mounted on the spindle by thermal shrinking. The bond can be released by pressure-oil injection without affecting the joint surfaces.
  • The rotor with sleeve is pre-balanced and can be removed and subsequently remounted
  • The rotor with sleeve is finished-machined - that is, the rotor outer diameter need not be finished after mounting.
