1PH2 built-in motors for SINAMICS S120/SIMODRIVE 611 производства Siemens

1PH2 built-in motors are used for machines requiring excellent machining quality, accuracy and running smoothness.

• Turning machines
• Grinders

• 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.

Typical speed/power graph for AC motors¹⁾

The graph shows the typical relationship between motor speed and drive power for 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.

¹⁾ For further configuration information, see the 1PH2 Motors Configuration Manual.

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.
