Traction induction motor

open access: yesMATEC Web of Conferences, 2018
The paper presents a traction induction motor with an innovative rotor winding design. The winding of the rotor is almost identical to the armature winding in the dc traction motors, with the exception of commutator. Winding is double layered.

A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

open access: yesSmartBot, EarlyView.
Electrostatic clutches offer programmable variable stiffness for multi‐DOF robots, but their continuous motion is usually bottlenecked by spatial constraints and detachment delays. Here, the authors report a compact annular electrostatic clutch joint with a biphasic amplitude‐frequency modulation strategy to rapidly mitigate residual polarization ...

Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

open access: yesSmall, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

The Host‐Guest Assemblies of Metal–Organic Frameworks and Protic Ionic Liquids With ZIF‐8 and [Dema][TfO] – Structural Response and Ionic Conductivity

open access: yesSmall, EarlyView.
MOFs can serve as effective proton conductors owing to their porous structures and well‐defined channels. In this study, the protic ionic liquid [Dema][TfO] is introduced into ZIF‐8 cages. The confined [Dema][TfO] can transfer between adjacent ZIF‐8 cages, inducing cage expansion through the swing effect.
