    AI Overview
    The 21A 19A frame motor appears to be a specialized DC motor, specifically used for between-glass blind systems (also referred to as blinds-in-glass or integrated blinds). 
    This motor is designed to drive blinds that are sealed between panes of glass, offering a compact, low-noise, and energy-saving solution for motorized window treatments. 
    Key Features of Between-Glass Motors (21A/19A Type) 
    • Application: Specifically designed for "between glass" blind systems, allowing for remote or automated control of sealed blinds.
    • Components: Often includes a DC motor, a PCB control board, and a shock absorber for smooth operation.
    • Performance: Features a low-noise, lightweight design meant for easy installation within window frames.
    • Variants: These are often categorized under A-OK Motor products for Venetian blinds or general window automation. 
    Note on Similar Terms: The results also indicate a potential, though unlikely, confusion with high-power AC motor drives (e.g., a "19A output current" VFD) or motor grader hydraulic components. However, the "21A 19A" combination listed together strongly suggests the window blind motor application.

    What is the difference between a JM and JP frame motor?
    For pump-specific motors, NEMA developed the standard around two different shaft lengths: JM (short) and JP (long). The shorter JM requires the use of a mechanical seal, while the longer JP shaft extension allows for the use of packing.May 5, 2020
