Von Weise VW62 Motor
Heavy-duty greenhouse vent actuator. We sell em, we replace em, and we rebuild em in-house. Across the US and Canada.
The VW62 in Plain English
The Von Weise VW62 is a heavy-duty linear actuator. People in the greenhouse world know it as the workhorse motor that drives roof vents, sidewall vent assemblies, and curtain systems. You’ll find them in commercial greenhouses, conservatories, and a lot of older controlled-environment setups.
Look, ventilation in a greenhouse is everything. When the airflow goes off, temperature spikes, humidity goes haywire, and your plants start stressing within hours. That’s the reason growers keep coming back to the VW62. It cycles all day, every day, and it doesn’t give up after a season like a lot of cheaper motors do.
Why Growers Like It
Heavy-duty build
Solid housing, real gearing inside. It’s made for repetitive cycling, not the once-a-day kind of work.
Sealed against moisture
Greenhouses are brutal on motors. The VW62 casing keeps out the humidity, the condensation, and the dust.
Smooth motion
The torque output stays steady, which means the vent arms and brackets don’t get hammered every cycle.
Reasonable on power
Strong mechanical output without pulling extra juice. Adds up across a multi-zone facility.
Where You’ll See Them
- Roof vent drives on commercial and older greenhouses
- Sidewall vent and louver automation
- Curtain and shade systems
- Replacing tired actuators on Lord & Burnham, Mark II, and similar setups

How to Tell Your VW62 Needs Help
- Vent’s not opening or closing all the way, or stalls mid cycle
- Grinding, buzzing, or clicking sounds it didn’t used to make
- You can see moisture inside, rust, or burn marks on the body
- Keeps tripping the breaker on the vent circuit
- The motor’s clearly working harder than it should, vent arm looking stressed
Catch this stuff early and you save yourself a much bigger repair. A motor that gives up halfway open can rip up vent arms and linkages on the way down. Most VW62s we get in can be rebuilt, so don’t just throw it out before having a look.
Install & Service
The VW62 uses standard mounting and plays nice with most greenhouse controllers. We always recommend a real installer do the swap, mainly because bad wiring or a misaligned mount is the number one cause of premature motor failure. Honestly the motor itself is almost never the problem when one fails early.
FAQ
Will a VW62 fit my current setup?
Most of the time, yes. It uses standard mounting and wiring. Send us a couple photos of the old motor, the nameplate, and the vent linkage. We’ll confirm before you buy anything.
Can my old VW62 be rebuilt instead of replaced?
Often, yes. The gearbox, housing, and shaft usually outlast the brushes and seals. We open it up, see what’s going on, and tell you straight whether it’s worth rebuilding or it’s time for a new one.
How long does a rebuild take?
Usually 5 to 10 business days from when we get the motor. Sometimes faster, depending on what parts we need to source.
Do you ship to Canada?
Yes. We ship parts and accept repairs from across both the US and Canada all the time.
I’m not even sure what motor I have. Help?
No problem. Take clear photos of the motor body, the nameplate, and the wiring, send them over, and we’ll identify it for you.
