DESCRIPTION:
The MSK 4310 is a complete 3 Phase Brushless Motor Speed Controller in an electrically isolated hermetic
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 4310 has good thermal conductivity of the
output switches due to isolated substrate/package design that allows direct heat sinking of the hybrid without
insulators.
