Going form 0.09KW up to 2.2KW, this motor covers a pretty wide power band for small power tools and light machinery — we've seen them used on bench grinders and small pumps mostly, but they'll handle a bandsaw or a fan just fine.

You're looking at speeds between 1330 and 2800 RPM depending on the exact model, and aluminum housing means it doesn't weigh as much as an iron frame would, which helps if you're fitting it into something you move around.

MY Series Electric Motor

But it's not suited for heavy indutrial loads running 24/7, teh protection class tops out at IP55 so it's fine for dust or splashes but you wouldn't sink it.

Motor Internal Components

Insulation can be either Class B or F depending on what you order, and the winding is 100% copper — we've pulled a few apart and can confirm it's consistent, though the effiency figures (48% to 73%) aren't going to win any awards.

Motor Performance Chart

Every unit ships with a COA and carries CE and CCC marks, so customs clearance is usually straightforward, but check the lead time if you need IP55 specifically — we stock IP44 and IP54 more often.

It's built for continuous S1 duty, and the starting torque comes in at about 1.7 to 1.8 times the rated value, which is good enough for most loads that don't require a massive jolt to get moving.

Frequently Asked Questions

What are the minimum order quantities for the MY series motors?

We typically require a minimum order of 50 units for standard models like MY561-2 or MY90L-4. For smaller test orders, we can sometimes negotiate, but stock availability may vary.

Do you provide CE or CCC certification documents with shipments?

Yes, we include copies of CE, ISO9001, and CCC certifications with each shipment. Just let us know in advance if you need the originals or notarized versions.

Can the insulation class be mixed between B and F within the same order?

We can customize the insulation class per unit, but mixing classes in a single batch would require a separate production run. Standard is B class, but we can switch to F if you specify.

What's the lead time for a 2.2KW, 4-pole model with B5 mounting?

For a standard MY90L-4 with B5 flange, lead time is around 15-20 working days after order confirmation. Rush orders might be possible if we have stock, but that's rare.

Are the motors packed for long-term storage in humid conditions?

We pack them in sealed cartons with desiccant bags, but for storage over 6 months in high humidity, we recommend adding a VCI bag or storing in a climate-controlled area. The aluminum housing helps, but moisture can still affect the windings.

While the delivery was surprisingly swift, arriving well ahead of the estimated schedule, the packaging left much to be desired. The outer box was quite battered, though fortunately the internal padding prevented any visible damage to the motor itself. Upon inspection, the build quality appears robust and exactly as described, with clean finishes and proper insulation classification markings clear. The service aspect was standard; communication was functional but not particularly proactive. Overall, a satisfactory transaction where the product quality met expectations, but the shipping care could be improved to match the speed of delivery. The motor seems well-suited for its intended industrial application, and the ordering process was straightforward without any complications or delays on the administrative side. It was a purchase that fulfilled the basic requirements efficiently.
