    The datasheet you linked clearly says the max output current for your receiver is 5mA, which is not enough for a motor. You need an external PNP transistor with a pullup resistor to Vcc on its base pin, which will also connect to the receiver output. Drive the motor by a connection to ground and the power line connected to the emitter. Collector to Vcc.

    You need to buffer the output with a transistor, replace the buzzer for your motor.

    buffer use a 1K resistor for R3, and omit R2.
