Mounting the sevcon gen4?

Ryan Sweet All Messages By This Member #30616 How have you folks mounted the sevcon controller? With the heat sinks on there doesn’t seem to be a natural way to mount it. Do you put it on rods? Or mount it with the heat sinks up against a panel? Pictures anyone? Thanks!
Darin All Messages By This Member #30617 Ryan, I did not use a heat sink and haven't had any problems with it getting warm.? FWIW, I have a 37 ft sailboat with the same 10kW Thunderstruck kit I think I saw that you are using.? I typically run the motor around 30 to 60 amps, and have taken it up to 125 amps or above for 10 minutes or so without ever having an overheating problem with either the motor or the controller.??

Michael Ryan All Messages By This Member #30618 Ditto I have been using a Gen 4 Sevcon without a Heat Sink for two years and overheating is not a problem. It will depend on the rating of your Sevcon, but heat dissipation?will be improved if your mount it to aluminum?plate with a large surface area. Forced air over the heat sink is also another option. toggle quoted message Show quoted text On Mon, Jul 13, 2020 at 4:16 PM Darin <armyofpenguins@...> wrote: Ryan, I did not use a heat sink and haven't had any problems with it getting warm.?

Thierry All Messages By This Member #30619 Dear Ryan, The first question is whether the SEVCON GEN4 controller heats ... A simple 6mm aluminium sheet can be used as a support and heatsink:? With a heatsink slightly larger than the controller, it is possible to first attach the heatsink and then the controller to the heatsink:? Caution: The heatsink fins must remain vertical in the direction of the natural air flow. And when the motor mount is designed to accommodate the controller, it's easier!?? Thierry
Larry Brown All Messages By This Member #30620 开云体育 I mounted the sevcon and 2 of the TS2500 chargers on a sheet of aluminum bent into a u shaped stand. ?I bolted the sevcon to the aluminum with the heat sync on the back side with thermal grease on each surface. ?Based on others' comments I get the impression this was overkill but I figured if I'm going to give it my best shot, why not. ? toggle quoted message Show quoted text On Jul 13, 2020, at 5:15 AM, Thierry <thierry.lequeu@...> wrote: ?Dear Ryan, The first question is whether the SEVCON GEN4 controller heats ...

Darin All Messages By This Member #30621 I should clarify that my gen4 is mounted on stainless steel sheet, which acts as a heatsink itself.? I've attached a sketch.? Hope this helps.?

Bob Jennings #30622 I used the optional heat sink. It was short money when I purchased the 10kw kit. Not sure if it makes?a difference but the controller is mounted in the engine compartment so figured it couldn't hurt. toggle quoted message Show quoted text On Mon, Jul 13, 2020, 1:09 AM Ryan Sweet <ryan@...> wrote: How have you folks mounted the sevcon controller?

Larry Brown All Messages By This Member #30624 开云体育 These were taken during the install. ?The backside where you can see the heat sync if you notice the nuts on the right side they are the bolts holding the chargers on the back side. ?They also have thermal grease between the aluminum plate and the aluminum stand. toggle quoted message Show quoted text On Jul 13, 2020, at 6:48 AM, Bob Jennings <heatnh@...> wrote: ?

Reuben Trane All Messages By This Member #30625 I have a bulkhead just aft of the motor. I cut out a section to match the heat sink. I mounted the Sevcon on the forward facet of the bulhead with the heat sink penetrating into an open area over the shaft. Works like a champ.?
Harley Clark #30630 The GEN4 is mounted on an aluminum plate offset?by square tubing. I felt more comfortable with this set up even though i was not planning on using more than 50 amps out of my 48 volt lithium?battery pack. toggle quoted message Show quoted text On Mon, Jul 13, 2020 at 1:55 PM Reuben Trane via <rjtrane=[email protected]> wrote: I have a bulkhead just aft of the motor.

Damon Lane All Messages By This Member #30632 Similar to the people who used channel, I installed the controller on the heatsink and then to a bulkhead with standoffs to create an air gap.
