15V TO 60V – THREE PHASE BRUSHLESS DC MOTOR PRE DRIVER

15V TO 60V – THREE-PHASE BRUSHLESS DC MOTOR PRE-DRIVER

The project presented here is a three-phase BLDC motor pre-driver. The project consists of 3x half-bridge IR2101 driver IC and 6 channel high current N-MOSFETS. The project can be configured as 3 independent half-bridges H-bridge for a brushed DC motor, or a single high current brushless motor driver. The rotor position can be detected using 3 hall sensors assembled in the motor. Hall-effect […]

ANOTHER OMNIBOT 2000 UPGRADE

ANOTHER OMNIBOT 2000 UPGRADE

There were many toy robots back in the 80s that were — frankly — underwhelming by today’s standards. Back then, any old thing that rolled around with some blinking lights would impress, but the bar is higher today. Then again, some of the basic components won’t really change. You still need wheels, motors, batteries, and
