Peripheral used for motor control:

  • Opto Isolated PWM

  • CAN bus

Peripheral use for ESC telemetry:

  • Serial RS-232

  • Serial RS-485

  • USB

Any of the serial interfaces can be used to configure the internal variables of the MC110.

The ESC includes an internal SD memory which is used to record operating logs. The variables to store can be selected through the corresponding interface.

Note

The selected configuration interface cannot be used to send telemetry.

    Note

    Power depends on kind of motor, motor speed, battery voltage and current comsuption).

  • Sensorless mode: MC110 is able to operate with sensorless motors with maximum efficiency.

    Note

    The sensorless mode does not require a minimum speed to measure it and operate, as long as MC110 provides current to the motor phases (since the speed is measured with the current)

  • Data recording

VCC

This is the main power input for the secondary part of the driver. It must be powered with a voltage of 8 to 20 V.

The consumption of this pin also depends on the loads connected to 5 V pin.

Interfaces

HALL Inputs

Warning

The employed hall sensors must not exceed 5 V.

These inputs are used to add to the system a feedback in sensored mode (incremental type, usually magnetic).

The 3 Hall efffect sensors must be placed at 120º (Electrical degrees) of each other. The following is a simple formula for obtaining the mechanical degrees of separation when installing the sensors:

\[Electrical \ Degrees = Pole \ Pairs \times Mechanical \ Degrees\]

So the sensors must be placed one of each other at:

\[Mechanical \ Degrees \ (º) = \frac{120º}{Pole \ Pairs}\]

For example, for 10 pole pairs:

\[\frac{120º}{Pole \ Pairs} = \frac{120º}{10} = 12 º\]

Example diagram

Tip

The arc length between sensors can be calculated with the following equation:

\[Arc \ Length = \frac{2 \times \pi \times Motor \ Radius \times Mechanical \ Degrees \ (º)}{360}\]

FAN_PWM

This 0-3.3 V output is used to control an external fan if needed. External power for the fan is required, and it is important that the GND connection of this supply is the same as the GND connection for the supply of the control group (user connector).

Opto PWM Input

This input is an optocoupled control digital signal.

The input is interpreted as 0-100 % of the maximum RPM. An initial dead band can be configured to prevent the engine from starting.

NTC/PTC Input (External Temperature Sensing)

A PTC or NTC can be integrated.

Warning

The PTC or NTC must not exceed 5 V.

The PTC/NTC should be connected on the low side of an external resistor divider. This is the configuration by default. A high side connection can be used too, but a custom modification is needed.

The isolated Voltage_ref output should be left floating in default mode. The iso_ground is the return path of the NTC/PTC sensor.

ERROR SIGNAL

This signal indicates if there is an error within the MC110. A positive voltage of 3.3 V means that there is no problem.

SIN/COS_SIGNAL

These signals are those dedicated to the SIN / COS type analog sensor.

Warning

SIN/COS signals must not exceed 5 V.

USB

This is the interface normally used to configure the MC110 internal parameters.

The connection and disconnection of the USB related signals should always be done when the power supply (via the VCC input) is on.

Note

Not recommended for sending telemetry by default.
