Product Details

Brake motors are required when you want the motor to stop quickly even with heavy inertia/load like hoisting, positioning or material movement. "mototek" brake motors are becoming popular due to its practically maintenance free and noise less performance. "mototek" Brake motors are normally supplied with D.C. fail safe brakes, also known as normally ON brake. The motor is braked (Locked) when power is not applied i.e. de-energized to brake. This ensures real fail safe braking. The construction is quite robust and requires very limited maintenance. With wearing of liners on the rotor of brake, the air-gap can be easily adjusted. lf necessary, the rotor can be easily replaced completely as well. The brake is mounted on end covers on non-driving end of the motor. lt comes with a Manual release lever.

Selection Criteria

It is recommended to use proper size of brake. It should not be undersized or should not be over sized as well. Depending uponthe application, the service factor of the brake has to be selected for proper braking.
Service factors for selection for the brake are mentioned in the selection table. This is just a guideline as there are many other factors to be considered while selecting the brake size like mounting positions, type of transmission and type and ratio of reductions. We request you to consult "mototek" for proper selection of brake size.

SUPPLY

Unless otherwise specified, brake voltages are 190 V DC with a rectifier of 415V A.C. dual phase input and 190V DC output duly fitted on the motor and properly connected with the terminals. For faster brake releasing action, 96 V D.C. brakes can be used with the some rectifier.-but with an input supply of 230V AC. Brakes with 24V or 48 V DC can be supplied but without rectifier. For these supply voltages brake, inbuilt rectifier is not available. Hence the brake has to be energized and de-energized external supply and controls.

SWITGHING

Motors are connected with AC switching as standard. For faster action i.e. reduction in the delay time in operation, DC switching can be used. Care must be taken while DC switching as it generates heavy sparking across the making and braking contacts which can lead to shorting of switching contacts and ultimately leads to failure of contact making or braking. This may become a cause of accident in some cases. Hence suitable universal shock suppressors and capacitors can be used which are normally not included in the "mototek" motors. Fast acting rectifiers are also available as well. Alternatively, 3 phase AC brakes can be used as well.

AIR-GAP ADJUSTMENT

The air gap between the armature of the brake and the plates is important as the braking torque and engage and disengage time of the brake. lt is recommended to verify and if required to adjust the air-gap periodically for consistent performance. It will not only improve the braking performance but will also increase the life of liner. The Brake is mounted on the rear end cover of the motor with three to six ellen bolts "L" near the outer periphery of the brake as indicated n the figure. These ellen bolts “L'' pass through hollow hex bolts "H" which are in the opposite direction of the ellen bolts "L". Moving plate "M" is located between the armature and brake coil housing which moves axially during operation of engaging and disengaging. The air gap between this moving plate "M" and brake coil housing has to be maintained. It can be measured with a filler gauge or any other suitable measuring system. To set the air gap, loosen all the ellen bolts "L" and unscrew all the hollow hex bolts "H" slightly to increase air gap and tighten them to reduce the air gap. Tighten the ellen bolts "L" and measure the air gap near the bolts if required adjust the air gap again to achieve specified air gap as mentioned in the table.

OPTIONS

AC fail safe brakes and Normally off (energized to brake) brakes in different operating voltage can be supplied subject to confirmation. Motors with shaft extensions on rear side can be supplied if required for manual operation. A small handle can also be provided.

LENGTH OF BRAKE MOTORS

Dimensions of the brake motors are same except the total length. Length will be longer than the standard motors. Tentatively it will be as indicated in the table for motors with DC or AC fail safe brakes. For other types of brakes, please confirm the same.
