DESCRIPTION:
The MSK 4324 is a complete 3 Phase MOSFET Bridge Brushless Motor Control System in a convenient isolated baseplate package. The hybrid is capable of 10 amps of output current and 200 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 4324 has good thermal conductivity of the MOSFETs due to a hermetic isolated package design that allows direct heat sinking of the hybrid without insulators.
