Page 79 Connecting motors in series For the following reasons, Siemens only conditionally recommends connecting motors in series: • The required flow rates of the motors must be approximately the same (< a factor of 2) • An increase in the cooling water temperature can result in having to derate the second or third motor if the maximum cooling water inlet temperature is exceeded.
Page 80 Mechanical properties 4.1 Cooling Cooling water inlet temperature Note Cooling water inlet temperature Select the cooling water inlet temperature so that condensation does not form on the surface of the motor. Cooling water temperatures which are lower than the ambient temperature tend to result in increased water condensation.

Page 84 You can use equivalent products from other manufacturers. Siemens does not accept any warranty for the properties of third-party products. Maintenance and service Check the level and discoloration or turbidity of the cooling water at least once a year. In addition, every year carefully check as to whether the cooling water still has the permissible specification.

Mechanical properties 4.2 Degree of protection Coolant connection: See table "Cooling data and sound pressure levels" The units should be connected with hoses to provide mechanical decoupling (refer to the table "Materials and components of a cooling circuit").

Page 97 Mechanical properties 4.4 Types of bearing For specific applications, the grounding of the motor Z can be more unfavorable than the grounding of the connected loads Z , e.g. for long motor cables and when the motor is mounted in an insulated fashion. In this case, the capacitive discharge (leakage) current of the motor flows from the motor frame through the motor shaft to the connected load and from there to ground.

Mechanical properties 4.6 Mounting of rotating unions on 1PH8 hollow-shaft motors Shaft end The DE shaft end is cylindrical in accordance with DIN 748 Part 3 (IEC 60072-1). Mounting of rotating unions on 1PH8 hollow-shaft motors General information 1PH8 main motors with a hollow shaft (13th position in the Article No.: " 3 ") are designed as main spindle motors for machine tools and machining centers with internal tool cooling.
Page 99 Mechanical properties 4.6 Mounting of rotating unions on 1PH8 hollow-shaft motors With opening seals, the sealing surfaces are separated when there is no coolant pressure, e.g. during a tool change. In this case, coolant runs out of the supply line and out of the motor shaft through the opened seal.
Page 100 Mechanical properties 4.6 Mounting of rotating unions on 1PH8 hollow-shaft motors Figure 4-11 Mounting the rotating union Figure "Mounting the rotating union," illustrates how an axial force arises due to joint pressure, for example, in the gap between the motor shaft (hole bolt) and the spindle shaft. This acts upon the motor shaft against the bearing preloading force F .

Page 206: Procedure When Engineering
Configuration 6.2 Procedure when engineering Procedure when engineering 6.2.1 SINAMICS configuring procedure Motion Control 1PH8 motors are optimized for motion control applications. They execute linear or rotary movements within a defined movement cycle. All movements must be performed in a time- optimized manner.
Page 207 Configuration 6.2 Procedure when engineering Clarification of the type of drive The motor is selected on the basis of the required torque, which is defined by the application, e.g. traveling drives, hoisting drives, test stands, centrifuges, paper and rolling mill drives, feed drives or main spindle drives.
Page 208: Specifying The Duty Cycle
Configuration 6.2 Procedure when engineering The following operating scenarios have been defined: • Duty cycle with constant ON period. • Duty cycles with varying ON period. • Free duty cycle. The objective is to identify characteristic torque and speed operating points that can be used as a basis for selecting the motor depending on the load.
Page 209 Configuration 6.2 Procedure when engineering Duty cycles with varying ON period As well as continuous duty (S1), standard intermittent duty types (S6) are also defined for duty cycles with varying ON periods. This is a mode of operation consisting of a series of similar cycles, each one comprising one time period with a constant load and one idle time.
Page 210 Configuration 6.2 Procedure when engineering Free duty cycle A load duty cycle defines the characteristics of the motor speed and the torque with respect to time. Figure 6-3 Example of a duty cycle A load torque is specified for each time period. In addition to the load torque, the average load moment of inertia and motor moment of inertia must be taken into account for acceleration.

Page 214: Different Rated Points For Induction Motors
