Siemens 1PV5135-4WS28, 1PV5135-4WS24, 1PV5138-4WS24 Technical Manual

I’ve been doing this long enough to know that the difference between a motor that runs for ten years and one that burns up in six months is often a set of torque values that someone decided to eyeball. This 16-page Siemens 1PV5135-4WS28, 1PV5135-4WS24, 1PV5138-4WS24 Technical Manual puts the factory data in your hands. Zero guesswork. Aftermarket knockoffs are worthless.

Torque and Power Curves for All Three Models

Each model gets its own torque-speed curve page. The 1PV5135-4WS28 hits 360 Nm max torque at 250A, with a continuous rating of 160 Nm. The 1PV5135-4WS24 pushes 370 Nm at 300A, same continuous torque. The 1PV5138-4WS24 is the big one: 530 Nm max at 300A, rated torque 220 Nm, rated power 85 kW. These curves show you where the motor saturates. If you’re sizing a drive without this data, you’re flying blind.

What Coolant Does the 1PV5135-4WS28 Require?

Water-glycol. The manual specifies it for all three models. Don’t substitute straight water or automotive antifreeze unless you match the exact mix. Ambient temperature range is -30°C to 70°C, so your cooling loop has to handle that. The manual gives you the data points to verify your system.

16 Pages of Factory-Sourced Data

Sixteen pages sounds thin, but every page packs a punch. You get the electrical ratings: rated voltage DC (520 V or 650 V depending on model), rated current, max speed (10,000 rpm for the 1PV5135s, 9,000 rpm for the 1PV5138). Physical dimensions: 425 x 245 x 245 mm for the smaller two, 510 x 245 x 245 mm for the 1PV5138. Weight: 90 kg vs 120 kg. Protection degree IP65 / 9k. This is all the data you need to verify the motor fits your application.

Verify the Ambient Temperature Limits Before Installation

All three models share the -30°C to 70°C ambient range. If your enclosure sits in direct sunlight or near a heat source, you need to derate. The manual doesn’t give derating curves, but it gives the base limits. Push beyond that without factory support and you’re on your own. I’ve seen too many motors cooked because someone ignored the temperature spec.

IP65 / 9k: What the Protection Rating Means

IP65 means dust-tight and protected against low-pressure water jets. The ‘9k’ is a Siemens identifier for high-pressure washdown capability. This does not mean submersible. If you’re installing in a washdown environment, make sure the connectors and seals match. The manual states the rating clearly, but you still have to follow the installation guidelines.

Factory Specs Only – No Aftermarket Shortcuts

This is a direct Siemens PDF, not a third-party reprint. The same document used by Siemens engineers. Compare that to something like Drogobych Crane КТА-16, КТА-25, КТА-28 2004 Installation Manual – also OEM, but for a completely different application. For vehicle transmission work, you might reference Manual Transmission specs, but that’s a different world. Even a Manual Transmission has its own torque limits, but this motor is a different beast. Other industrial manuals like Injectocean Diablo, Murciélago, Defender, Discovery, Freelander Technical Manual cover vehicle systems, not these drive motors. The Minsk MMVZ-3.11212 Technical Manual – Factory Specs is another example of a factory document, but again, different sector. Stick with Siemens for Siemens motors.

Is this manual available in English?

Yes, the PDF is in English with some German labels. 16 pages.

Does it cover the 1PV5138-4WS24 model?

Yes. Page 3 is dedicated to the 1PV5138-4WS24 with its own torque-speed curve, rated power 85 kW, max torque 530 Nm @ 300A, and weight 120 kg. All three models are included.

What torque values are listed?

The manual shows max torque and continuous torque for each model at specific current levels. For the 1PV5135-4WS28, max torque is 360 Nm at 250A. The 1PV5135-4WS24 max torque is 370 Nm at 300A. The 1PV5138-4WS24 max torque is 530 Nm at 300A. These are factory ratings, not estimates. You also get the torque-speed curves plotted on pages 1-3, so you can see how torque drops off as speed increases. That’s critical for sizing a drive.

What is the cooling requirement?

Water-glycol. The manual specifies it clearly. Ambient temperature range is -30°C to 70°C.

This is the kind of documentation that keeps a motor running at peak efficiency. If you’re responsible for a Siemens drive motor installation or maintenance, you need the factory data. Access the Factory Manual from the link above and keep it on your bench.
