New JMAG Ver.24.1 Out Now
In April 2025, JMAG-Designer Ver. 24.1 was released.
JMAG is being developed to automate design. To this end, Ver. 24.1 has even more improved functionality. In particular, the motor temperature evaluation function has been greatly upgraded.
This section picks up on the functional improvements and new features in Ver. 24.1.
JMAG Database
Provide a knowledge base for systematically accumulating and utilizing design insights.
By integrating simulation databases from various models, an environment is created where design knowledge can be systematically accumulated and utilized across different product lines.
Explorer Optimal Design with JMAG Design Explorer
We provide a JMAG Design Explorer, a tool for comparing and evaluating design proposals.
The accumulated information and past analysis assets can be evaluated collectively in JMAG Design Explorer to narrow down the most appropriate design proposal across different models.
Driving Mode Calculation Considering Temperature Change
Temperatures can be evaluated during driving cycle and continuous rated operation.
By automatically coupling efficiency map analysis and thermal analysis, the temperature of each motor part can be evaluated, taking into account the change in loss accompanying the temperature rise during driving cycle.
N-T and Efficiency Map Calculation Considering Temperature Constraints
N-T curves and efficiency maps can be drawn taking into account the temperature rise during continuous rated operation.
The thermal circuit function has been enhanced to perform these evaluations with high accuracy and to make it easy to create models.
Enhanced Thermal Circuit (Refrigerant Temperature Increase / Effect of Motor Bench / Bearing Model)
Shaft cooling and cooling jackets can be reproduced more closely to actual cooling conditions by taking into account temperature changes in the refrigerant.
It also provides motor bench and bearing thermal circuit components available only with parameter settings.
Generation of Thermal Circuit Models for System Simulation
Thermal circuit models can be generated for system simulations.
Thermal circuits created and analyzed in JMAG can be converted to MILS (Simscape) models with a single click, making it easy to perform thermal system simulations using JMAG-RT models as heat sources.
Magnetic Design Scenario of Axial Flux Motor
Design proposals for axial flux motors can be explored.
With the addition of magnetic design scenarios for axial flux motors to JMAG-Express, design exploration can now include the number of poles and slots as design variables.
