Descripción
This tender focusses on the identification of electronics supplier that design and produce "Off the Shelf" tunable controlers to control the shaft position of brushless actuators.
Title
French major aerospace company looks for permanent-magnet synchronous brushless motor controllers
Abstract
Electrical actuators are thoroughly used for various space transport actuation chains like Thrust Vector Control of the launcher or cryo engines control. Most of them are used in a position control mode, the controlled angular position being measured with resolvers embedded in the actuator.
For various needs, COTS (Commercial Off-the-shelf) controllers can be considered:
• during early phases of the development, it is necessary to use easily tunable controllers to prototype or contribute to the qualification of the actuator while the avionics is not yet available
• during production phase, acceptance tests of subsystems do not require a flight worthy electronics and COTS controllers are relevant with common bench digital interfaces.
Nice to have/ to know:
• Some COTS controller are qualified for harsh environment and could offer the possibly of "Flight" use. This is not considered as a formal need for this tender Some typical environmental requirements are therefore provided herein. (refer to § Technical specification )
• The capability of the supplier to customize its products for specfic needs would be appreciated (to be mentioned in the answer)
Functional requirements :
• Motor topology: 3-Phases
• Control:
- Positon controller
- Tunable vector control algorithm with HMI interface
- Loop bandwidth : position>5Hz, speed >30Hz, current >4 kHz
• Communication: either CAN, CANopen, RS232, RS422, USB, Ethernet
• Inputs:
- Minimal / Nominal/Maximal supply voltage (VDC) = (40, 140, 200)
- Minimal / Nominal/Maximal logic voltage (VDC) = (10, 28, 70)
• Ouputs:
- Minimum continuous power output (W) = 3000
- Sinusoidal continuous RMS current limit (A) = 40
• Encoders:
- type : résolvers
Supply Current(mA) : [30; 80] ( typical)
Supply Voltage : 5 V – 8 kHz
• Casing dimensions:
- Volume < 5L
- Weight <5 kg
Environmental requirement (nice to have) :
