MotorSolve v2.5 Now Available

Summary of Major Changes
  • New interior and exterior BLDC wound rotor template
  • Improvements to the robustness of the Variational Geometry engine and the use of the VG constraints.
  • Separated the core and tooth in the templates for better result reporting
  • Many more refinements to the charting, results and material sections
MotorSolve version 2.5 is now available. Maintained clients can visit to download the software or read the Release Notes for full details.

To request an evaluation, live demo or pricing information, please contact your local Infolytica Corporation representative.

LiveDocs for MotorSolve BLDC Online

Coinciding with this release of MotorSolve is the launch of LiveDocs for MotorSolve. In addition to the basic and general information available in the MotorSolve Help, the MotorSolve Live Docs provide in-depth information allowing one to gain better control and understanding of many MotorSolve's advanced features, such as:
  • The Variational Geometry engine, and the way it manages protected and unprotected dimensions;
  • The Sizing feature, and its benefits illustrated with an accompanying example;
  • Stator winding aspects discussed in great detail, including
    • Angular spread
    • Winding factors
    • Automatic and manual coil layout
    • Back EMF approximate calculation
  • Motion Analysis parameters explained and illustrated
  • PWM Analysis aspects such as
    • Current regulation and its implementation
    • Some sample results
  • D-Q Analysis sample results
  • Lumped parameters Analysis example
  • Fields and Fields Charts sample results
  • Specific motor concepts are also discussed, such as
    • General PWM
    • Torque and cogging torque
Maintained MotorSolve clients can visit to access the new Live Docs for MotorSolve BLDC.

Wound Rotor Synchronous Machine for Traction Application

The cross section of a 4 HP wound field induction motor. This example illustrates the utility of considering wound rotor synchronous machines for traction applications. An example of an 8 pole 48 slot wound rotor motor is considered for traction based on the design of a similar interior permanent magnet (IPM) machine

Flux weakening of variable speed drives and comparison of CPSR in synchronous machines

Comparison of constant-power speed range (CPSR) in synchronous machines In this example, using MotorSolve, design and comparisons of CPSR characteristics are made between this example, using MotorSolve, design and comparisons of CPSR characteristics are made between a fractional slot (2/7 slot per pole per phase (SPP) SPM), a multi-layer IPM and an integral slot (1 SPP) machine.

BLDC Motor Design Workshop with Jim Hendershot

Pre-Conference Workshop at Motor and Drive 2011
February 28, 2011  - Full Day Workshop - San Antonio, TX
$695 USD


The workshop will focus on practical problems faced by real designers in their work environment. Jim will discuss the design process based on the motor specifications provided by the attendees and guide you through the process of obtaining a motor that meets the requirements.
  • Design specification
  • Getting an initial design
  • Improving performance with each design iteration
  • Performance profile of your motor
Jim has over 40 years experience in the field of manufacturing and designing electric motors. With past key employments at United Technologies, General Motors, Clifton Precision, Berger Lahr & Pacific Scientific, he has designed hundreds of motors.
