MotorSolve - DCM

PMDC and Wound Field Motor Design Software


MotorSolve DCM is the only motor design software you need to get an accurate and complete prediction of your machine's performance. Our powerful automated finite element analysis engine is embedded inside, therefore no model exporting or additional software is required.

Overview

MotorSolve DCM uses a template-based interface which makes creating new designs from scratch effortless - just enter the number of rotor and stator poles and then specify information such as:

  • Outer diameter
  • Stack length
  • Configuration of the brushes and commutator
  • Winding
  • Lamination material
Features

MotorSolve DCM is the easy-to-use software for modelling, simulating and predicting the performance of brushed DC, permanent magnet DC (PMDC), wound field and universal motors. The software has been tailored with a motor designer's needs in mind, making it easy to analyse and optimize any of the motor topologies supported by the DCM module.

The rapid and accurate results are based on automated FEA simulations. There are different analysis methods included, which gives the user control the level of refinement (accuracy vs time).

Templates and Design Parameters

  • Brushed DC, PMDC, wound field and universal motor templates
  • For wound field: series, shunt and separately excited
  • Geometric dimensions of the armature and stator
  • Number of rotor and stator poles can be arbitrarily large
  • Polyphase machines supported
  • Select laminations, brushes and wire materials from extensive database

Motor Analysis

MotorSolve DCM calculates machine performance based on automated finite element analysis simulations. There is no need to construct the model, perform mesh refinements and extensive post-processing to extract motor related results. MotorSolve performs these operations for the user.

Using the template interface, a desired waveform, quantity or field is selected with the operating conditions specified.

ANALYSIS TYPES

Current-driven analysis
  • Models the DC supply as a constant current source. This allows the simulation to converge much more quickly to the steady-state
  • Ideal for servo applications where the motor is controlled by a PWM drive to achieve a specified torque

Voltage-driven analysis
  • Perform a full time-stepping non-linear FEA simulation
  • Highly accurate for all types of operating conditions and ideal for final design verification
