When buying an AC electric motor, choosing the right supplier matters as much as the motor itself, because a wrongly specified motor creates ongoing cost in both energy and maintenance. This article covers where and on what criteria you should buy an AC motor.

From the Supplier or a Reseller?

Buying an AC motor directly from the supplier gives an advantage in technical support, warranty and spare-part access. As an Izmir-based supplier that both builds and sells the motor, DRG Motor can offer direct technical guidance on the power and speed best suited to your application.

What to Ask When Buying

To buy the right motor, define the application first: the driven machine, the required power (kW), the speed (2-pole 3000, 4-pole 1500, 6-pole 1000 rpm) and the ambient conditions. From these you set the IP55 protection rating, Class F insulation and the mounting (foot-mounted B3, flange-mounted B5, face-mounted B14).

Don't Skip the Efficiency Class

The most often overlooked criterion in a purchase is the efficiency class. Under IEC 60034-30-1, IE3 Premium and IE4 Super Premium motors cost a little more upfront but repay the difference through energy savings under continuous duty. For hard-working applications a higher class should be chosen.

Sourcing from DRG Motor

To buy an AC motor with confidence, stock status, warranty and delivery time must be clear. Share the power, speed and frame you need, and DRG Motor will provide the suitable model, the current price and the delivery time.
