Reading: Siemens can provide a range of motors from ordinary asynchronous motors to servo motors to meet the drive needs of various industries. Specific to the machine tool industry, because the machine tool is a device for manufacturing production machinery, it has high requirements for accuracy and dynamic performance. Therefore, the motor used on the machine tool is mainly a servo motor. The Siemens servo motor currently used in China is mainly 3? Kind: 1FT5 Siemens servo motor, 1FK6 Siemens servo motor, 1FT6 Siemens servo motor.
The 1FK6/1FT6 motor is combined with the SIMODRIVE 611D/611U to form a digital drive system. Siemens servo motors can be connected to digital control systems with digital interfaces, such as Siemens' SINUMERIK 802D/810D/840D/840Di systems.
In 2001 Siemens introduced a new servo motor series: 1FK7 Siemens servo motor. 1FK7 Siemens servo motor was developed on the basis of 1FK6 Siemens servo motor. The mechanical interface is completely compatible with 1FK6 Siemens servo motor, but its performance has been improved. Let's take a look at the 1FK7 motor.
Currently used 1FK6 servo motor is divided into two basic types and high dynamic performance type.
1FK7 Siemens servo motors are still divided into two categories when they are introduced: CT type and HD type.
CT is an abbreviation for English Compat, which is compact.
HD is the abbreviation of English High Dynamic, namely high dynamic performance type.
There are differences in the applications of CT motors and HD motors:
CT-type motors are mainly used in occasions with narrow installation space and are suitable for most industrial applications; HD-type Siemens servo motors are mainly used in production machines with high requirements for dynamic performance.
If divided according to the shaft height, 1FK7 Siemens servo motors are available in 6 types of 28mm, 36mm, 48mm, 63mm, 80mm and 100mm. The 1FK6 motor does not have a 28mm shaft height motor.
Siemens has a variety of drives that can be used with 1FK7 Siemens servo motors, including:
810D internal drive, SIMODRIVE 611D servo drive, SIMODRIVE 611U servo drive, MASTERDRIVE MC engineering inverter and POSMO distributed drive.
The upper control system can be selected according to the application. If the drive system is used on the machine, Siemens' SINUMERIK CNC systems (eg 802D, 810D, 840D) can be selected; if the drive system is used on a general production machine, Siemens SIMATIC can be used to program Logic controller.
Performance characteristics:
There are three types of Siemens servo motors currently used in China: 1FT5 Siemens servo motor, 1FK6 Siemens servo motor, and 1FT6 Siemens servo motor. 1FT5 Siemens servomotors and SIMODRIVE 611A cooperate to form an analog drive system, which can be connected to a digital control system with analog interface, such as Siemens SINUMERIK 810/850/880/840C; 1FK6/1FT6 motors and SIMODRIVE 611D/611U cooperate to form a digital drive system Siemens servo motors can be connected to digital control systems with digital interfaces, such as Siemens' SINUMERIK 802D/810D/840D/840D systems.
