Carpanelli self-braking motors: normal brake or positive brake?
Carpanelli self-braking motors: normal brake or positive brake?
Carpanelli self-braking motors are a highly reliable solution for all applications requiring rapid stopping, operational safety and positioning precision.
One of the distinctive features of the range is the possibility to choose between a normal brake (power failure) and a positive brake (power supply).
What are self-braking motors?
Carpanelli self-braking motors incorporate an electromagnetic brake mounted on the rear of the motor.
The brake has the following functions:
- Ensuring the immediate stopping of the shaft
- Keeping the load in a stable and secure position
- Improving precision in work cycles
- Preventing unwanted movements in the event of machine stoppage or emergency
Carpanelli designs compact, quiet self-braking motors that are also suitable for harsh environments, with customised options available on request.
Motors Normal brake and positive brake: what are the differences?
Normal brake (power failure)
This is the recommended brake when safety is a priority, and the most widely used in industry.
- The brake is active when there is no power
- When the motor is powered, the brake opens.
- When the power is removed, the brake engages immediately and locks the shaft.
Advantages:
- Maximum safety in the event of a power failure
- Ideal for keeping the load in position when the motor is stopped
- Perfect for systems where protection against unwanted movement is necessary.
Applications:
- Lifting
- Vertical automation
- Packaging machines
- Inclined conveyors
- Industrial doors and shutters
- Handling applications with risk of load falling
Positive brake (when power is present)
Less common, but very useful in specific cases. It is the right brake when operational flexibility is required.
- The brake is active only when powered.
- When the power is turned off, the brake is deactivated and the shaft is free.
Advantages:
- Allows manual movement of the load when there is no power supply
- Perfect for applications where locking must occur only on command, not automatically
- No risk of unwanted locking during manual operations.
Applications:
- Systems that require freedom of movement when the motor is off
- Machinery where locking is only needed during a specific phase of the cycle
- Light automation
- Manually adjustable devices (industrial curtains, mechanical adjustments, small actuators)
