Cold stair lift motor

How cold is cold, 32F or 50F or what? Also, the figure was a little confusing!!! Is the battery connected to charge at both the top and bottom? If so, then light could be on whenever the battery is being charged, but off when in motion,

What happens if the room is cold and you selectively heat only the bearings/gear box with hot air?

Is it the motor that is the problem or the batteries? The way I read this is the batteries are the problem. A PTC heater and some good insulation would seem to be the better answer.

Normal winter night temp in the stairway is 25-45, with a few nights

Charging contacts are at top and bottom. Chair is at top nearly all the time.

Only need resistor or lamp on when charging.

motor housing to keep the temperature about 40degF. The unit is in an unheated area and temps get too low for the motor to turn normally. I considered an electric blanket or pad but having an elderly person messing with something on the stairs is not a good idea. Also, there's the issue of having a separate part and cord to deal with.

this when setting up electronic devices in remote locations, installed in an insulated box with a car battery & resistor. In this case a night light bulb might be another choice.

It keeps the grease from getting hard.

The heat would be for the lubrication in the motor and gears. Heat for battery is not needed.

Thanks everyone.

So clean off this cheapo grease and replace with cold-adapted alternative?

Yes, that's by far the best idea but next to impossible to get to where the grease is without major disassembly. And that's nothing compared with putting it all back together again.... I did a partial disassy once before which took a good 2 days. Chair was originally installed on the right side of the stairs and had to move it later to another stairway on the left side. Everything had to be switched to the other side. I still can't believe we did it and got everything back working.

Get some low temperature grease and oil for your motor and gearbox - there are synthetics that cover a wider range than regular oils and grease.

Check with the manufacturers of the chair lift - they may have recommendations in this matter.
