Braking / Soft Start Devices
Brake & Soft Start Devices: Protection, Control and Energy Efficiency
Our brake and soft start devices combine gentle starting, controlled stopping and effective braking of electric motors with asynchronous operation – all in a maintenance-free, compact device.
Functional Scope and Benefits
- Soft start reduces inrush current and avoids mechanical stress
- Soft stop reduces the coasting torque at the motor output
- DC brake brings the motor safely and quickly to a standstill
- Microcontroller-based control for flexible setting of starting and braking parameters
- Wear-free and maintenance-free – ideal for retrofitting in existing systems
Typical Applications
- Drives with high moments of inertia such as fans, pumps, conveyor belts and centrifuges
- Machines for the wood-processing industry (e.g. saws, grinding machines)
- Safe motor stop required, for example during hazard detection or emergency tripping
- Use in automation projects with microcontroller control
Special Technical Highlights
- Separate setting of starting and braking behavior
- Integrated protection functions such as phase failure and motor temperature monitoring
- Devices with integrated bypass reduce power losses in continuous operation (e.g. BL 9028) :contentReference[oaicite:0]{index=0}
- Compact modules, also with integrated Modbus or CAN interfaces (e.g. VersiComb II Safe) :contentReference[oaicite:1]{index=1}
- Modern thyristor control (SCR) minimizes grid interference and voltage jumps :contentReference[oaicite:2]{index=2}
Whether for gentle starting or safe braking – our combinable soft start and brake modules offer reliable motor protection, higher system availability and easy integration into your control infrastructure.
