Product Description:
The MK20EYYYYA-101 by Pacific Scientific is an AC servo motor built for controlled motion applications. It is engineered with a permanent magnet design that ensures reliable operation under continuous duty cycles. The motor is designed to deliver accurate and stable rotation performance, which suits precision motion tasks. It integrates features that align with current industrial automation needs.
The MK20EYYYYA-101 AC servo motor delivers a rated power of 0.23 kW and operates at a rated speed of 4500 rpm. The motor runs on a rated voltage of 310 V and draws a rated current of 1.2 A. It supports a maximum current of 5.7 A, which provides additional torque when needed. The maximum torque under intermittent operation is 2.2 Nm at S3-2 % duty. The motor uses a resolver as the sensor type that offers durable and accurate feedback under continuous motion. The insulation class is rated as F, which ensures heat resistance under electrical stress. The enclosure carries an IP 85 protection class that defends against solid intrusion and low-pressure water. The insulation and protection ratings ensure a longer motor lifespan under electrical and operational loads. The motor includes an integrated holding brake rated for 1.2 Nm torque. The brake operates on 24 V and consumes 0.33 A during actuation. The holding brake improves axis stability during motor downtime or emergency stop conditions.
The permanent magnet rotor technology in the MK20EYYYYA-101 AC servo motor cuts down on losses when changing speeds over and over again. The design includes effective electrostatic control that makes it possible for torque to be generated smoothly when the load changes. The speed feedback is based on a 1X-RX setup that keeps tracking of the location stable. The high speed rating helps systems that need to work quickly while still being accurate.
Frequently Asked Questions about MK20EYYYYA-101:
Q: Why does MK20EYYYYA-101 use a 310 V rating?
