Melville, NY – CD-adapco has released the new 9.1 PC-BDC version of SPEED with over 150 revisions and updates added to extend, amplify and broaden the program’s capability and ease-of-use. PC-BDC is intended for designing and calculating brushless PM motors, drives and generators, line-start PM motors, and wound field synchronous machines. The accelerated speed of the PC-BDC program’s motor design solutions is aided by the ability to choose from 42 major embedded magnet shapes plus many subtypes and 13 stator slot shapes. SPEED’S philosophy is to include all the main known analysis techniques in combination with specially developed calculations via a single user interface that connects to finite element analysis (FEA) support.

The PC-BDC program provides multiple methods for computing the brushless PM motor’s performance including torque, speed, efficiency, power, current, waveforms of current, EMF and torque. The program provides a wide range of graphic plots to assist the designer to gain a global look at the design’s performance.

The electronic drive is modeled in some detail with peak, mean and RMS currents computed for a range of different drive circuits (power devices plus diodes) and control strategies. The static solution procedures calculate the brushless PM motor performance using a forced ideal current waveform to compute the performance at a single operating speed point at a fixed temperature. The program’s dynamic design process integrates the voltage equations and calculates the motor’s current and torque waveforms taking into account the dynamic effects of inductance and EMF waveforms.
