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:

1. 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.
2. 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.
3. High dynamics: An extremely fast control loop for phase currents ensures precise current control and very rapid response to changes in control signals.
4. 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.
5. 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.

Product variants

The Manufacturer Part Number (MPN) completely specifies the product type and version. When combined with the Firmware Identifier (Basename), it can serve as the ordering code. The MPN is made up of different sections, which are explained in the table below. Typically, only the standard variant is in stock.

MPN of the standard variant: AX_05kxa0810-800_00000-000BB

Main PCB assembly variant

Power Stage

Usually defines a variant of the power stage, occasionally can indicate a special version of the product's PCB.

info

The particular controller's voltage variant usually uses different MOSFETs based on the given voltage range.

Available versions are:

• 06: Standard version of the controller. Indicates 6 MOSFETs in the power stage.

• 05: Special version of the controller. Indicates lower performance power stage.

Power Features

Defines variant of the powering interface

Available versions are:

• d: Standard version of the controller. This version does not have any additional features.

• k: Special version of the controller. Interal LM5017 supply is replaced by LM5008 chip

Connectivity

Defines variant of the communication interface

Available versions are:

• x: Standard version of the controller. Used communication interfaces are USB, CAN and UART.

Motor sensors

Defines supported motor position sensors. More infornation about the particular motor postion sensor interface can be found in this section.

Available versions are:

• a: Standard version of the controller. Supports 3 Hall and Sin/Cos motor position sesnors.

Voltage

Defines voltage operation range of the controller. Detailed technical specifications can be found in this section.

info

The higher the limit voltage range, the better the protection against overvoltage. However, as the voltage range increases, the MOSFETs' Rdson also increases.

Available versions are:

• 08: Standard version of the controller. The absolute voltage limit is 80 V.

Current

Defines current measurement range of controller.

info

The higher the current measurement range, the better the protection against overcurrent. However, as the current measurement range increases, the resolution of the current measurement decreases.

Available versions are:

• 10: Standard version of the controller. The measuring range is 100 A.

HW configuration

Internal HW configuration describes selectable modifications in hardware. Each item can be present (marked with 1) or absent (marked with 0). A 12-bit binary number is used for this description and is visualized in hexadecimal form. Not all the options are used, these items are marked as "Reserved".

Powering on method

The device offers several powering methods, defined by the combination of these items:

• Internal Fuse
• One button control
• Constant ON

A detailed powering scheme together with the available powering options can be found in the powering circuit's detailed specification.

Power supply option

Defines isolated supply voltage level

• 1: 10 V output.

CAN terminator

The device has a selectable internal 120-ohm termination resistor. A detailed CAN interface scheme can be found in the CAN communication interface.

Connected grounds

It is possible to connect two grounding potentials together by the internal jumper.

ODIN configuration

Defines configuration of pull-up and pull-down resitors for ODINs.

Finish

Housing

Defines housing option.

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.
