MicroMag Receiver

The mMag Receiver, here with the ESC, is small
16 x 18 x 4 mm3 and light,
A 3 Channel FM Receiver with SMD micro crystal and integrated
electronics for the truly proportional control of two magnet actuators. All
electronics integrated on one tiny PC board weighting not more than
The receiver bandwidth is not quite as narrow as that of a standard
receiver, so the operation in a 20 kHz grid is recommended.
Microprocessor
The receiver has a microprocessor that automatically detects the motor
channel and the neutral stick positions during the first second of start-up. This
allows the use of any brand of standard FM model control transmitter without
any adjustments. On these functions patents are pending. Switch on the
transmitter with the throttle closed then switch on the receiver. It is
important that low throttle yields a short pulse time as required by all
ESC’s to get a fail safe when the transmitter signal drops out.
When the receiver/motor battery is plugged this should be done without
hesitation. When not the microprocessor can hang in its boot phase. When the
system does not start-up properly: simply remove the battery wait for 5 seconds
and plug-in again.
Speedcontroller
The receiver has one output that can accept the mSpeedcontroller
that has been developed in conjunction with this receiver. A standard
speedcontroller can not be used with this receiver as the output also contains
the neutral information and is thus not compatible with standard
speedcontrollers or servo’s.
