In most cases, direct current motors running on battery power with an output higher than 300W cannot be switched-on directly. To limit the starting current, resistors are used then.
These resistors are switched-off after finishing the motor start-up procedure so that no battery energy is needed for the resistor during motor operation. A switchgear is required to switch the resistance levels.
Permanently switched-on resistor
These resistors are designed for permanent operation with the rated current. They are switched-on during the entire motor operation and therefore require battery energy during operation.
- robust design
- tailored to the WINKELMANN-motor
- the testing of the entire drive, consisting of motor and resistor, is carried out at the premises of WINKELMANN
- detailed adjustment of the resistor to the customer requirements, e. g. limitation of the starting current to the 2,5 times rated current
