Create a brush DC motor controller circuit
$15-25 USD / saat
Hi
We need a motor controller circuit to a product we are developing. The circuit will control a brushed DC motor in both direction, have a tri-color LED, HM-10 Bluetooth module, 3 buttons, DC power plug, 2x IR sensor and a ATMEGA328 MCU. It will also handle an external joystick and 2-phased encoder.
Some issues:
- The motor has around 12A (at 12V) stall current, this must be handled as the PSU stops providing power over its limits resulting in a restart of the MCU. The MCU must be operational, so the circuit must have limitations so the motor can’t draw all the power.
- The motor will change directions up to 5 times per second. The circuit must handle the induction produced in the motor when changing direction.
- We have not selected power supply yet. It is up to a 24V-5A or a 12V-8A PSU. The 12V PSU is cheaper so we prefer to select that one. You will help us select the best one for our application.
- The motor controller needs to be cheap and handle high frequency PWM from the MCU. Minimum around 5k Hz and preferred up to 62.5kHz. We prefer an integrated IC H-bridge circuit design for motor controlling. We have used a simple custom MOSFET H-bridge on our previous versions, but they have proven to slow for our PWM.
- There are strict rules to where the components shall be placed. We have previous GERBER and other files of our older prototype circuits so you can copy a lot of the design from there.
- We need the circuit fast
- We want the circuit to be as cheap as possible.
To get this job, you must be experienced in handling MCU, and preferably with the ATMEGA series. You must also have experience with motor controlling IC and H-bridges. You must also be able to start on this job right away.
Best regards,
Lars
