10 AMP, 55V, 3 PHASE

BRUSHLESS MOTOR

SPEED CONTROLLER

EQUIVALENT SCHEMATIC

DESCRIPTION:

The MSK 4410 is a complete 3 Phase Brushless Motor Speed Controller in an electrically isolated low cost

package. The hybrid is capable of 10 amps of output current and 55 volts of DC bus voltage. Included is all of the

bridge drive circuitry, hall sensing circuitry and commutation circuitry. Also included is a user programable current

limit circuit and a tachometer circuit for closed loop operation. The MSK 4410 has good thermal conductivity of the

output switches due to the isolated substrate/package design that allows direct heat sinking of the hybrid without

insulators.
