Application
The electric motor driven actuator EMS
18/C is used in combination with a BST
control unit and a mechanical guiding
device anywhere where correction of
the position of running webs, e.g.
paper, plastic materials, rubber, textiles,
etc., is necessary.
The complete connection-ready design
enables fast and inexpensive installation in appropriate systems, and is
especially suitable for upgrading or
replacement in existing systems.
Special Features
? Complete actuator with maintenance-free drive
? Plug-type connection
? for curved and linear positioning
? various combinations of stroke,
positioning force and positioning
speed are possible
Included Parts
Actuator EMS 18/C, comprising:
? electric motor
? integral absolute position detection
? housing block with bearing and
gearbox
? ball screw with push pipe
? final position damping
? mounting bolts
Calculating the Nominal Positioning Force
The nominal positioning force FN of the
actuator must exceed the break-away
force FL of the equipment to be moved.
Calculation of the break-away force FL
[N]: FL = G * μ0
G total weight of the equipment
μ0 friction coefficient
(e.g. 0.1 with reel friction
