Description
M37 Variable Speed Modification + LiftMaster GSD Mechanical Operator
- M37 replaces the AC motor and control circuit in a door operator with a DC variable speed drive control and permanent magnet DC motor.
- May be supplied for either 115VAC 1Ø or 230VAC 1Ø power.
- Allows adjustment of door speed over a wide range. Dual-speed applications may be possible with faster open cycle and slower close cycle.
- Acceleration adjustment gives “ramp up” or soft starts to allow operation of very heavy doors. Dynamic brake and current limit circuits replace mechanical brake and clutch respectively, minimizing the number of moving parts that may wear out. Suitable for continuous‑duty and high-cycling applications.
- Please note that this modification will usually affect the horsepower selection for a given model. Higher speeds require higher horsepower for the same door.
- WARNING: Safety equipment must be used with door operators employing this modification
