8200 motec – Overview
The concept of the 8200 motec frequency inverter is
based on the modular system of complementary
components for distributed drive systems. When used with
a Lenze geared motor or Lenze three-phase AC motor, the
inverter forms a high-performance electronic variable
speed drive. These robust drives can be used for speed
control in the most varied of industries and areas of
application, including conveyor technology, HVAC
engineering, automation, etc.
In addition to the features listed under the product
information for distributed drive solutions, the 8200 motec
frequency inverter is characterised by the following
features:
Vector control
– 180% torque
– High speed control range – up to 1:50 without feedback
– Extremely smooth running
– Torque setting range up to 1:10
Versatile
Many different types of three-phase AC motors can be
controlled:
– Three-phase asynchronous motors
– Three-phase reluctance motors
– Medium-frequency motors
It couldn't be easier to retrofit/expand systems
To operate the 8200 motec, no additional control voltage
other than the mains supply is required. This means that
systems which were previously uncontrolled can be
retrofitted for process with relative ease.
Adaptable
The selectable form of the V/f characteristic enables the
frequency inverter to be adapted to loads with constant or
square-law torque.
Optimised performance
The performance of the frequency inverters can be
optimised by operating them at increased rated power.
This creates the following advantage:
– A high-performance motor can be used in
continuous operation
Applications: e.g. pumps, air conditioning systems, etc.
Braking
You can use a brake rectifier (see Accessories) to supply
power to and control an electromagnetic spring-operated
brake directly from the 8200 motec.
