MSK4460 Evaluation Board User's Guide Rev A
By Bob Abel & Dan Williams, MS Kennedy Corp.; Revised 9/19/2013
Introduction
The MSK 4460 is a complete 3 Phase MOSFET Bridge Brushless Motor Control System in
an electrically isolated low cost package. The hybrid is capable of 10 amps of output current
and 55 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 4460 has good thermal conductivity of the MOSFET's due to
isolated substrate/package design that allows direct heat sinking of the hybrid without
insulators.
The evaluation board provides a platform from which to evaluate new designs with ample
real estate to make changes and evaluate results. Evaluation early in the design phase
reduces the likelihood instability, or other issues, from becoming a problem at the
application PCB level.
This application note is intended to be used in conjunction with the MSK4460 data sheet, so
please reference the data sheet for additional application information and specifications.
Setup
Use the standard 4mm banana jacks to interface with the assembly to connect to your power
supply and motor assembly.
