Product overview
Product description
siliXcon brushless motor controllers are a key component of a system that effectively controls three-phase motors. They are intended to operate with low-voltage DC power sources and are available in various voltage options, providing versatility and flexibility. Due to these features, siliXcon motor controllers are primarily used in battery-powered vehicles that require compact dimensions. Key features of siliXcon motor controllers include:
- High power density: Advanced technology and an emphasis on efficient heat dissipation from the most stressed areas allow us to maintain the control unit's dimensions as small as possible.
- Modularity: Individual blocks of the control unit are designed as modules that are shared among various controller models and variants. This provides users with a high degree of flexibility, and transitions between models do not pose complications.
- High dynamics: An extremely fast control loop for phase currents ensures precise current control and very rapid response to changes in control signals.
- Advanced protective features: Thanks to precise control of phase current and temperature control at critical points, the controller is robustly protected against overcurrent and overheating.
- VCU (Vehicle Control Unit): Integration of a high-performance microprocessor allows the implementation of vehicle control functions directly into the controller, thus saving installation space and end-application costs.
The controller is primarily designed to drive an electric motor with permanent magnets. Two standard FW applications LYNX and OPHION can be loaded into the controller.
AX controller
This compact 2.6kW brushless motor controller, classified among the smallest products in our portfolio, features an efficient design and durable aluminium housing. With a maximum output peak phase current of up to 70 Arms, it provides reliable performance for small electric motor control. The single signal connector (Molex iGrid) ensures easy installation, bringing convenience and efficiency to a wide range of applications.
The controller is depicted below with the marking of its main parts.
| Position | Name |

| 1 | Motor connector - Amass MR60 |
| 2 | Battery connector - Amass XT60 |
| 3 | Product label |
| 4 | Status LED |
| 5 | Signal connector - Molex iGrid 36 |
| 6 | Mounting sourface |
Signal part is connected via the signal connector - 5. Battery is connected via XT60 connector - 2, and phases via MR60 connector - 1. The controller should be installed by placing the mounting sourface - 6 on a flat metal sourface and securing it by four screws. Status LED - 4 indicates error states.

Accesories
Signal connector
- mating housing: Molex 5016463600
- crimp terminals: Molex 5016471000
- crimp tool: Molex 638192300
Signal connector sealing
The controller's signal connector sealing is designed as a separate part to keep the controller dimensions as small as possible. It is installed on the signal connector cables (see drawing)
The product number for purchasing: AX_signal_sealing.
The controller fulfils the environmental specification only if this sealing is properly installed.
AX Molex holder
This tool helps you to assemble an AX connector with the sealing. The AX Molex holder holds the Molex connector with the sealing, so you can easily insert wires with crimp.
You can download the model here: AX Moler holder and 3D print the holder.
Pre-crimped wires
siliXcon can provide pre-crimped wires for end-application prototyping. The bare wires with iGrid crimp on one end can be purchased by following ordering codes:
