Resolver connection
Only for BAMOCAR-PG-D3-RS
The resolver is an absolute measuring system for one
motor revolution.
It is robust and insensitive to high engine
temperatures.
The design corresponds to a rotating transformer.
The rotor is fed by the reference (10 kHz).
The stator supplies the sine and cosine signals
modulated by the rotational frequency.
In the servo amplifier, the amplitudes of these signals
are evaluated and digitised.
The resolution is automatically set to 10, 12 or 14 bits.
The maximum possible speed is 50 000 rpm
(10 bit).
The digitised signals are used for the pole wheel
angle, the position control, the speed control and for
the incremental output.
Socket on the unit
Only use motor with 2, 4, 6 or 8 pole resolver approved by the manufacturer.
