Simple, sturdy, and economical

Delivered in IP23 enclosures, the starting resistors are calculated for each application and then manufactured in our workshops from stainless steel.
The result: starting resistors that provide identical starts, faithfully accompanying even the harshest processes | vibrations, humidity, corrosive atmosphere, heat, cold, dust, etc. The boxes are sized for a number of starts and a timing period and are protected in case of overrun.

Advantages of Delta resistors

• Initial power supply to the motor at reduced voltage
• Takeoff torque adjustment
• Smooth ramp-up
• Economical
• Quick and accurate startup analysis
• Maintenance-free

Shunt or slightly compound excitation motors

The calculation of times and resistances is the same as for slip ring motors: the aim is to limit the very high starting current. To do this, several resistance sections are inserted in series with the inductor, which will be operated at each time. The resistance of the starter is lowered as the starting current decreases.

Series or Compound Excitation Motors

Starters for this type of motor are special applications. This requires precise knowledge of the characteristics (torque/current curve, internal resistance, armature reaction).
