The starting resistors for starting electric motors in industrial equipment are used to:
- Limit the starting current of the motors
- While maintaining strong torque
They are particularly used in the following applications
- heavy industry ,
- mines & quarries ,
- overhead cranes, cranes ,
- sawmills, etc …
Rotor starting resistors
For smooth and efficient starting of the slip ring motor
Rotor resistors are used for slip-ring motors which offer high starting torques. These engines offer possibilities of:
- fine tuning
- good Current / Torque linearity around the nominal current
The resistors are used to control the ring motor. Rotor start-up with Metal Deploye Resistor resistors is thus carried out in several stages, generally between 3 and 5 times. Which ensures smooth and efficient engine starting .
Without rotor starting resistors, the slip ring motor will start under unfavorable conditions: very low initial torque and inrush current 7 times greater than the nominal. Our resistors designed according to your needs allow flexible and efficient starting.
Functions and advantages of rotor starting
Suitable for industrial environments and very severe cycles
Wide range of power or voltage
High starting and braking rates
Possibility of replacing a FILREX, TOLREX La Thermostatique, SEIEM, GEC France, La Mécano Française brand devices
Rotor starting resistors for slip ring motors
Flexible start-up of equipment
A stator starting resistor plays an essential role in the control of electric motors, fans, compressors , etc …
It allows gradual starting, without jerks:
- avoiding hammer blows on the pipes
- by protecting the turbine of the pump
- by increasing the lifespan of the equipment
Indeed, integrated between the line contactor and the motor, it makes it possible to limit the starting current to 3.5 times the nominal current of the motor instead of 6 to 7 times during starting.
Reliable, robust and economical
It can be used in environments with the harshest conditions (unreliable electrical networks, high heat, humidity, vibrations, corrosive atmosphere, heat, dust, etc.)
Easy to install and use
A rotor starting resistor is easy to use:
- Limited starting current supply
- Simple installation and reduced maintenance
A complete range of resistors is available: braking, starting and traction
METAL DEPLOYE RESISTOR offers a complete range of resistors to control the motor of your equipment:
- Braking resistors , for correct operation of the drive in stop braking or braked operation
- Traction resistors, for powerful decelerations and regular braking
