The TB6612FNG motor driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes - CW, CCW, short-brake, and stop. The two motor outputs (A and B) can be separately controlled, the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode.
Logic supply voltage (VCC) can be in the range of 2.7-5.5VDC, while the motor supply (VM) is limited to a maximum voltage of 15VDC. The output current is rated up to 1.2A per channel (or up to 3.2A for a short, single pulse). Board comes with all components installed as shown. Decoupling capacitors are included on both supply lines. All pins of the TB6612FNG are broken out to two 0.1" pitch headers; the pins are arranged such that input pins are on one side and output pins are on the other.
- Power supply voltage: VM=15V max, VCC=2.7-5.5V
- Output current: Iout=1.2A(average) / 3.2A (peak)
- Standby control to save power
- CW/CCW/short brake/stop motor control modes
- Built-in thermal shutdown circuit and low voltage detecting circuit
- All pins of the TB6612FNG broken out to 0.1" spaced pins
- Filtering capacitors on both supply lines Dimensions: 0.8x0.8"
Sorry so many questions but I have only just discovered your V interesting site...... Can the vibrating 3vlt(max) motor be controlled using this contoller ? (assume I have taken off the asymetric weight which is usually not too difficult - GENTLY clamp the weight and with a slim punch, punch the motor shaft out ;-). If so what sort of minimum reduction can one expect Yes I know about gears and pulleys etc even mylar belt drive reductions but.... Thanks again
Posted byon Wednesday, 7 November 2012As long as the motor controller is run at 3V which it will work at then yes it could be used to control the 3V vibrating motor. The motor controller will handle an average max current of 1.2A and the vibrating motor only needs 75mA so plenty of spare current there. To answer your question, yes you can use this board to control the 3V vibrating motor. The gearing is a little harder to answer, as I?m not sure what your planning on doing with the motor. What I can tell you is that it spins at approximately 14,000 RPM. Because the motor is supplied with a cam and isn?t designed to be used unmodified, I can?t tell what the torque will be. You would need to do some experimenting to work this out.
