Overview
SIEMENS servomotors have been specially designed to satisfy the high requirements placed on variable-speed drives.
The high power density of the servomotors makes them extremely suitable for use in compact machines.
SIEMENS motors and SIEMENS drives are optimally matched to one another. The servomotors and SIMOVERT® MASTERDRIVES or SIMODRIVE® drive technology provide a powerful drive system for use in all industries.
Versions
Principal characteristics
Compact design
High power density and overload capability
High maximum speeds
Integrated encoder system
High dynamic response due to low rotor moment of inertia
Excellent concentricity properties
Rugged, almost maintenance-free design.
Synchronous servomotors - 1FK6, 1FK7, 1FT6, 1FS6
The special synchronous servomotors characteristics include:
High overload capability
High dynamic response
High static torque.
1FK6 and 1FK7 servomotors
The 1FK6 servomotors satisfy the requirements in the lower power range from 0.7 HP to 7 HP (0.5 kW to 5.2 kW). With their optimized design they are the most economical solution for many applications.
The new 1FK7 servomotors are based on the experiences gained with the 1FK6 range, and are especially characterized by:
An extremely high dynamic response (1FK7 HD, high dynamic)
Compact design (1FK7 CT, compact)
Expanded range of performances and options.
1FT6 servomotors - high performance
The 1FT6 servomotors can be used for extreme requirements in a power range from 25 HP to 61 HP (0.2 kW to 45 kW). These motors are available with self-cooling in protection classes IP 64 to IP 68, with separate cooling, or with water-cooling. The wide range of options means they are the optimum solution for many high-end applications.
1FS6 servomotors - explosion-protected
The 1FS6 servomotors are designed for use in Zone 1 hazardous areas. These motors conform to type of protection EEx de IIC T3.
Synchronous linear motors - 1FN3
The 1FN3 linear motors are especially characterized by
Outstanding dynamic response
Very high traversing velocity
Excellent precision
Non-wearing drive components due to contactless drive power transmission.
Asynchronous servomotors - 1PH7, 1PL6, 1PH4
The compact asynchronous motors supplement the synchronous servomotors for applications in the upper power range up to 844 HP (630 kW).
Versions:
Force-cooled 1PH7 motors in protection class IP 55
Water-cooled 1PH4 motors in protection class IP 65
Air-through and force-cooled 1PL6 motors in protection class IP 23
These motors permit the full rated torque throughout the entire constant flux range.
Depending on the requirements, the motors may be fitted with the appropriate options:
Encoders (incremental encoder HTL, resolver, sin/cos incremental encoder 1 Vpp, absolute-value encoder)
Holding brake.
Gearboxes can be mounted on all servomotors as required.
