Dynamic Motor Drive
DMDTM technology delivers motor efficiency gains for mobility and industrial applications without the cost and supply issues of rare-earth metals.
How Dynamic Motor Drive
DMD uses the same pulse-density concept of DSF and applies that to electric motors and systems. In essence, in response to a requested motor torque demand, Tula’s DMD algorithms operate intermittently at the torque which has the maximum efficiency.
When torque requests are low, the magnetic field is pulsed at optimal efficiency whereas in conventional motor operation, the efficiency is low at low torque.
In the efficiency graph, when torque requests are low, DMD operation pulses the magnetic field at optimal efficiency (orange) whereas in conventional continuous motor operation, the efficiency is low at low torque (blue) for the same speed of operation.
DMD software improves range, lowers cost and reduces rare-earth metal dependence of battery electric vehicles, motors and generators
Wherever motors, generators and compressors are used, DMD can improve application efficiency
