Key Features & Performance Benefits
Wide Variable Speed Range
When combined with a dedicated speed controller (e.g., Panasonic MGSD series), the M91Z90GV4GGA offers infinitely variable speed control from 90 to 1,400 RPM (50Hz) and 90 to 1,700 RPM (60Hz).
Built-in Tachometer Feedback
The motor incorporates an internal tachometer sensor for closed-loop feedback control. This ensures stable speed regulation—even when the power supply frequency fluctuates, the motor maintains consistent rotational speed.
Multiple Operating Modes
Supports various operation types including speed control (variable), braking, forward/reverse operation, and soft start and soft stop.
Compact 90mm Frame
The 90mm square frame size provides a balance of power density and installation flexibility, making it suitable for equipment with space constraints.
International Safety Certifications
Certified to meet global standards: UL/CSA (North America), CE (Europe), and CCC (China).
Pinion Shaft Configuration
Features a pinion shaft design with lead wire termination—ideal for direct integration with gearboxes or specific mechanical transmissions.
