5255529

What type of motor is this, and what applications is it suited to?

The Festo 5255529 is an EMMT-AS-100-S-HS-RMB servo motor with an absolute multi-turn encoder and an integrated holding brake. Its torque, speed, and position feedback capabilities make it suitable for controlled motion applications such as automated handling, packaging machinery, and positioning axes, subject to application-specific sizing.

What are the motor's rated power and torque values?

The motor has a nominal power rating of 1,450 W and a nominal torque of 5.1 Nm. Its standstill torque is 6.3 Nm, and its peak torque is 13.7 Nm. Peak torque should not be treated as a continuous operating rating.

What operating speeds does the motor provide?

The nominal rotational speed is 2,700 rpm, and the maximum rotational speed is 4,770 rpm. The separately specified maximum mechanical speed of 13,000 rpm is not the motor's normal operating speed limit.

What voltage and current ratings should be considered when selecting a drive?

The specified nominal DC operating voltage is 680 V. The nominal motor current is 3.5 A, continuous stall current is 4.4 A, and peak current is 13.7 A. Drive selection must also account for the motor's feedback interface, winding characteristics, and application requirements.

What position feedback does the motor use?

The motor uses an EQI 1331 inductive absolute multi-turn encoder with an EnDat 2.2 interface. It provides 19-bit resolution, 524,288 position values per revolution, and absolute position detection across 4,096 revolutions.

Does the motor include a holding brake?

Yes. The integrated holding brake provides 11 Nm of holding torque and operates at 24 V DC. Its specified current consumption is 0.75 A, with a power consumption of 18 W. The holding torque rating should not be interpreted as a continuous dynamic braking rating.

What are the holding brake's opening and closing times?

The brake has a specified separation time of 80 ms, closing time of 20 ms, and DC response delay of 4 ms. These values should be considered when coordinating brake operation with motor motion.

What electrical connector does the motor use?

The motor uses a 15-contact hybrid plug with an M23x1 connector system. A mating cable assembly must match the connector arrangement and the electrical requirements of the motor and selected drive.

What ingress protection ratings apply to the motor?

Protection varies by component and shaft configuration. The motor shaft is rated IP40 without a rotary shaft seal and IP65 with a rotary shaft seal. The motor housing, including connection components, is rated IP67. The housing rating should not be assumed to apply to the shaft.

What ambient temperatures can the motor operate in?

The specified ambient operating range is -40°C to 40°C. Operation up to 80°C is permitted with the stated derating of 1.5% per degree Celsius above 40°C. The storage temperature range is -40°C to 70°C.

Can the motor be installed at high elevations?

The maximum specified installation altitude is 4,000 meters. Starting at 1,000 meters, the motor requires derating of 1.0% per additional 100 meters. This reduction should be included when assessing the required motor capacity.

What mounting arrangements are supported?

The specified mounting arrangements are IM B5, IM V1, and IM V3 under EN 60034-7, and the mounting position is listed as optional. Mechanical fit, shaft alignment, and load compatibility should be checked for the intended installation.

What shaft loads can the motor accommodate?

The specified permissible axial shaft load is 200 N, and the permissible radial shaft load is 1,110 N. These limits are important when selecting couplings, pulleys, or other shaft-mounted components.

How is motor temperature monitored?

Motor temperature is transmitted digitally through the EnDat 2.2 interface. The motor has insulation temperature class F and a maximum specified winding temperature of 155°C. That winding limit is separate from the permissible ambient temperature.

Is the motor rated for continuous operation?

Yes. The motor has an S1 duty rating under EN 60034-1. Continuous operation must remain within the applicable torque, current, temperature, and installation limits, including any required derating.

How much does the motor weigh?

The Festo 5255529 has a specified product weight of 6.7 kg. This mass should be considered when designing mounting brackets and calculating the moving load if the motor is installed on a traveling axis.
