DESCRIPTION:
The MSK 4462 is a complete 3 Phase MOSFET Bridge Brushless Motor Control System in a low cost convenient isolated non-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 PWMing, the transistors are modulated in locked anti-phase (complementary) mode for the tightest control and the most bandwidth. Provisions for applying different compensation schemes are included. The MSK 4462 has good thermal conductivity of the MOSFETs due to isolated package design that allows direct heat sinking of the hybrid without insulators.
