Framo Morat MS12 612-MS-TE03 24V DC Mounted Gear Motor

Framo Morat MS12 (612-MS-TE03) Mounted Gear Motor 24V DC 17.00A

The Framo Morat MS12 (612-MS-TE03) is a slip-on planetary/spur mounted gear motor engineered specifically for tight envelope installations requiring high breakaway torque, rigid structural integrity, and bidirectional duty. Built on Framo Morat’s Compacta series platform, this drive integrates a high-density 24V DC permanent-magnet motor with a multi-stage enclosed gear train encased in a vacuum die-cast aluminum housing.

Rated at 24V DC and 17.00A, this electro-mechanical actuator delivers dynamic, reliable performance under severe duty cycles, resisting vibration, ambient mechanical stress, and voltage ripples commonly found in marine auxiliary machinery, offshore motion stages, and heavy material handling plants. Whether utilized for valve actuation, hatch positioning, or industrial automation gantries, the 612-MS-TE03 configuration guarantees repeatable torque transfer and positive shaft locking characteristics.

Technical Specifications

Terminal Allocation & Electrical Hookup

• DC Power (+ / A1): Direct positive supply terminal (24V DC). Connect via min. 2.5 mm² (AWG 12) oil-resistant flexible marine cable to mitigate line voltage drop.
• DC Power (- / A2): Direct negative return line (0V). Polarity inversion to A1/A2 yields bi-directional rotational reversal for opening/closing motions.
• Ground / PE Terminal: Direct grounding stud on internal chassis frame for EMI suppression and personnel protection.
• Limit Switch & Auxiliary Terminals (Configuration Dependent): Pin terminals for integrated micro-switches / end-position stroke limiters (normally closed dry contacts for cut-off interlock).

Frequently Asked Questions

Can the Framo Morat MS12 (612-MS-TE03) be operated on 12V DC?

No. The internal permanent magnet field and armature windings are calculated for nominal 24V DC. Operating at 12V DC will cause the motor to spin at roughly half speed with significantly degraded torque, leading to premature stall and excessive heat under load.

How is the rotational direction reversed on this motor?

Because this unit uses a 24V DC permanent magnet motor, reversing the output shaft rotation is accomplished by reversing the polarity (+ and -) across the power input leads.

Is this gear motor self-locking?

Depending on the specific multi-stage internal reduction ratio selected in the MS12 line, worm or high-ratio spur arrangements can provide dynamic or static resistance. If holding heavy suspended loads in place during unpowered states is required, verify whether your system setup utilizes the optional armature brake or self-locking ratio stages.

Does the MS12 require oil changes or routine relubrication?

No. Framo Morat Compacta MS12 drives are factory-lubricated for life using specialized long-life synthetic grease. Opening the gear chamber in the field without factory tools can damage the internal seals and void reliability.

What is the significance of the “166324 Pos:10” designation?

166324 represents the specific manufacturing/assembly reference number tied to the build specifications (gear ratio, shaft diameter, and terminal setup), while Pos : 10 identifies the batch line assembly position for total quality traceability. Ensure these identifiers match when ordering direct drop-in spares.
