WebJan 3, 2024 · 3 Answers. Trolleys with overhead wires often disconnect momentarily and the high inductance creates an arc of the same current that allows some continuity but with some drop of voltage or power. Whereas AC might cutout in < 10ms. But the real reason is DC traction motors have greater efficient torque needed to start. WebApr 12, 2024 · Siemens DC drive technology has helped increase efficiency and reduce engineering costs for decades. Featuring an advanced design that greatly facilitates configuration, installation, integration, commissioning and service, SINAMICS DC drives are perfectly aligned with DC motors, are highly dynamic, and increase overall system reliability.

WebSep 4, 2014 · As the DC bus voltage drops, the motor current will increase to maintain the same power at the motor. If you were to look at your incoming power to the drive with an oscilloscope, you would see the top of the waveform would be flattened slightly. This is an indication that your incoming power is being overloaded. WebAny other single phase motor type will result in failure of the motor, the VFD or both. But to answer your question, AC V = DCV/1.41, so if you want 220VAC, the DC V must be at least 310V. But here again are some potential pitfalls. "220V" is not a standard motor design voltage, it is usually 230V, so the DC voltage would need to be 324V minimum.
