- S2 Limited Duration Duty: Operation at constant load for a limited time, less than required for thermal equilibrium, followed by a rest period to equalize machine and coolant temperatures within a 2°C tolerance. Designated as S2 followed by running time (e.g., S2 30 min).
- S3 Periodic Intermittent Duty: Identical cycles of operation at constant load and rest, where starting current does not significantly affect overtemperature. Designated as S3 followed by the intermittency ratio, calculated over a 10-minute cycle (e.g., S3 25%).

D Series - Double Polarity Motors:
The D series motors are used in applications requiring two fixed speeds, achieved by switching the motor poles.

Special attention is needed during polarity switching due to the braking torque applied, which can affect the motor's operation and transmission sizing.

Operation:
The FM brake functions by using spring pressure to engage the brake when there is no power supply. When powered, the brake magnet attracts the moving coil, allowing the brake disk to rotate freely. Upon power loss, the springs press the moving coil and disk against the motor shield to stop the motor.

Brake Power Supply Types:
- Direct Brake Power: The brake coil is activated automatically when the motor is powered, and the brake disconnects. Upon motor power disconnection, the brake re-engages. The braking response time is influenced by the motor's inertia and stored energy, which varies per motor and cannot be predetermined.
- Separate Brake Power: The brake is powered via a rectifier from terminals separate from the motor. The stop time is independent of motor and load characteristics.
- Direct Brake Power with DC Side Opening: This setup allows for rapid braking contact on the rectifier, making the braking response time independent of motor and load characteristics and shorter than separate power setups.
- Separate Brake Power with AC and DC Side Opening: Similar to the direct power setup, this configuration prevents energy discharge into the rectifier during braking, extending its lifespan.

Brake Motors - Notes and Calculations
Specifications and Calculations:
The document outlines the specifications and calculations necessary for determining the braking moment (MB) for brake motors. The key factors influencing the brake's rating include the moment of inertia to be braked, the number of braking cycles per hour, the severity of the duty, and the required stopping times. The braking moment is calculated using the formula:
where K is the safety coefficient (≥2), Jtot is the total inertia of rotating parts reduced to the motor shaft, n0 is the motor shaft speed, tF is the braking time, and ML is the moment of load acting on the system.

Wear and Thermal Load:
The document emphasizes the importance of considering the wear of friction surfaces in relation to service intervals and the thermal load, which is the work that can be dissipated by the brake in relation to the load's moment of inertia and the number of cycles per hour. Special ambient conditions may require additional protections or corrosion proofing.

Special ambient conditions may require additional protections or corrosion proofing.
Verification of Heat Dissipation:
Each cycle transforms the energy of moving masses into heat by friction. The work done during braking (WB) is calculated, and the number of cycles per hour (Z) must be less than the maximum permissible for the selected brake type. If the calculated starting frequency (Z) exceeds the permissible limit, adjustments must be made to reduce the starting frequency or oversize the brake.
Each cycle transforms the energy of moving masses into heat by friction. The work done during braking (WB) is calculated, and the number of cycles per hour (Z) must be less than the maximum permissible for the selected brake type. If the calculated starting frequency (Z) exceeds the permissible limit, adjustments must be made to reduce the starting frequency or oversize the brake.
Starting Frequency:
The maximum starting frequency (Z) is determined based on the load and inertias using the formula:
where KJ and KM are coefficients related to the moment of inertia of the motor and load, MS is the motor starting torque, and Z0 is the starting frequency under load and inertia conditions. The calculated starting frequency must be less than the maximum number of cycles/hour allowed for the brake.
The maximum starting frequency (Z) is determined based on the load and inertias using the formula:
Z = KJ KM Z0where KJ and KM are coefficients related to the moment of inertia of the motor and load, MS is the motor starting torque, and Z0 is the starting frequency under load and inertia conditions. The calculated starting frequency must be less than the maximum number of cycles/hour allowed for the brake.
Recommendations:
If the starting frequency is close to the maximum permissible, it is recommended to monitor the motor windings' temperature using a bimetal cutout to prevent overheating.

Brake Work and Frequency Calculations
The document outlines the calculations for brake work and frequency in electric motors. It emphasizes that the maximum allowable work (WBmax) must exceed the calculated work. The number of permissible braking operations between two settings is determined by the formula N = W1 / WB, where W1 is derived from the brake type table.

The number of permissible braking operations between two settings is determined by the formula N = W1 / WB, where W1 is derived from the brake type table.
Starting Frequency
The maximum starting frequency (Z) is calculated based on load and inertia using the formula Z = KJ KM Z0 [h-1]. The coefficients KJ and KM are obtained from tables, and Z0 is the starting frequency without load. The calculated Z must be less than the maximum allowable braking operations per hour. If not, the brake cannot dissipate the generated heat, necessitating a reduction in starting frequency or an oversized brake.

Heat Dissipation Verification
During each cycle, the energy of moving masses is converted into heat through friction. The braking work (WB) is calculated, and the number of cycles per hour (Z) must be less than the maximum allowable cycles for the selected brake type. If Z approaches Z0, motor winding temperature should be monitored using a bimetal thermal protector.
