DESCRIPTION:

The MSK 4361 is a complete 3 Phase MOSFET Bridge Brushless Motor Control System in a convenient isolated

hermetic package. The hybrid is capable of 30 amps of output current and 75 volts of DC bus voltage. It has the

normal features for protecting the bridge. Included is all the bridge drive circuitry, hall sensing circuitry, commutation

circuitry and all the current sensing and analog circuitry necessary for closed loop current mode (torque) control.

When PWM'ing, the transistors are modulated in locked anti-phase mode for the tightest control and the most

bandwidth. Provisions for applying different compensation schemes are included. The MSK 4361 has good thermal

conductivity of the MOSFET's due to isolated package design that allows direct heat sinking of the hybrid without

insulators.
