Resistors
Technical basics
- Enclosure
IP 00 for control cabinet installation or IP 23 - Continous output
500W per resistor - Resistance values
10mΩ bis 20Ω, depending on motor frame size and permitted maximal starting current - Voltage range
24 to 1000 V
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.
Starting resistor
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.
Your WINKELMANN-Advantages
- robust design
- tailored to the WINKELMANN-motor
- detailed adjustment of the resistor to the customer requirements, e. g. limitation of the starting current to the 2,5 times rated current
- the entire drive unit, comprising the motor and resistor, is tested on-site at WINKELMANN
