# SA-002: Actuators (calliper motors)
|
|
|
|
## Responsibility
|
|
|
|
Two electromechanical actuators on the rear callipers clamp and
|
|
release the brake pads. Supplied (assumption): commercial component
|
|
from a Tier-1 supplier.
|
|
|
|
## Interfaces

|
| Interface | Type | Notes |
|
|
|---------------|--------------|---------------------------------|
|
|
| Power | 12 V, PWM | bidirectional for apply/release |
|
|
| Current shunt | analog | sampled inside the ECU |
|
|
|
|

- Max clamping force: 20 kN
|
|
- Apply time (0 → max): 600 ms
|
|
- Nominal current: 4 A
|
|
- Peak current: 30 A (brief)
|
|
- Temperature range: -40 °C to +85 °C
