Frequently Asked Questions
What is the main advantage of the resolver encoder in this motor?
The resolver encoder uses electromagnetic principles rather than optical sensing, making it inherently resistant to dust, oil, vibration, and extreme temperatures. This provides superior reliability in harsh industrial environments where optical encoders would fail.
What is the IP rating of this motor?
The ECM-B3M-E21310RS1 has an IP65 protection rating, meaning it is dust-tight and protected against low-pressure water jets from any direction when used with proper waterproof connectors.
Does this motor include a brake?
No, the "RS1" suffix indicates this model is without brake. For applications requiring position holding during power loss (such as vertical axes), select a variant with integrated brake.
What drives are compatible with this motor?
This motor is designed for Delta ASDA-B3 series servo drives, including ASD-B3-1021-L (pulse train), ASD-B3-1021-M (CANopen), ASD-B3-1021-F (EtherCAT), and ASD-B3-1021-E (EtherNet/IP).
