Yongming LKZ Liquid Aluminum Capacitors for Joint Motor Selection
2 reports · 2 sources
Yongming introduces the selection solution of its LKZ series liquid aluminum electrolytic capacitors for robot joint motor controllers, targeting space-constrained, high instantaneous current scenarios by using a single high-capacitance unit to reduce the number of parallel connections. Taking LKZ 100V 150μF 8×25 as an example, a single unit provides 150μF, typical ripple current 900mA, and ESR of approximately 0.20Ω; four units in parallel yield 600μF, which can be used for board-level filtering and transient energy storage evaluation. Yongming states that the above values are calculated values from an example project; specific parameters are subject to the corresponding datasheet and actual measurements. Selection must be verified in combination with the BOM, operating conditions, and whole-machine testing, and results may differ across projects. The manufacturer offers free samples and Demo board testing so that designs can be verified with real test data.

- How to Choose Capacitors for Robot Joint Motors? Yomin LKZ Liquid Aluminum Capacitor Solution for Space-Constrained, High Instantaneous Current Scenarios
The Yomin LKZ series of liquid aluminum electrolytic capacitors targets space-constrained, high instantaneous current scenarios in robot joint motor controllers, using a single high-capacitance unit to reduce the number of MLCCs in parallel. Taking the LKZ 100V 150μF 8×25 as an example, a single unit has a nominal 150μF, typical ripple of 900mA, and ESR of about 0.20Ω; four in parallel in the example reach 600μF. The solution can be used for board-level filtering and transient energy storage evaluation; whether it applies must be verified against the BOM, operating conditions, and full-system testing, and the manufacturer offers free samples and Demo board testing.

To address the selection challenges of space constraints and high instantaneous current in robot joint motor controllers, the Yongming LKZ series liquid aluminum electrolytic capacitors use a single high-capacitance unit to reduce the number of parallel connections. Taking LKZ 100V 150μF 8×25 as an example, a single unit provides 150μF, typical ripple 900mA, and ESR of about 0.20Ω; an example configuration of 4 in parallel reaches 600μF, which can reduce layout pressure. The solution also offers vibration resistance, wide temperature range, and low ESR; whether it applies must be verified against the BOM, operating conditions, and full-machine testing, and the manufacturer offers free samples and Demo board testing.
