The new high-performance braking system has been developed for use in crane systems, port facilities, ship winches, hoists, and belt conveyors. A new manual release has been designed specifically for this brake meeting the high requirements of the enclosure rating. The modular structure of the brake enables flexible use with single or dual rotor.

This brake is only to be actuated with a bridge half-wave rectifier (included in the scope of supply). The power input during the release is 440 W for 1.3 sec., then it is reduced to 110 W.
The spring-applied brake is designed for the conversion of mechanical work and kinetic energy into heat. Due to the static brake torque, the brake can hold loads without speed difference. Emergency braking is possible at high speed. The more friction work, the higher the wear.
- New braking system with a high performance and a sealed manual release, enclosure according to IP66
- Modular, 750 Nm with single rotor, 1500 Nm in dual rotor design
- Can replace existing brake solutions
- High degree of Corrosion-resistant by nitrided friction surfaces and zinc-coated magnet housing
- Energy-saving control by bridge/half-wave rectifiers
- Easy air gap check in the brake by check bore holes in the housing
- Accessories, optional, also retrofittable
- Non-contact sensor for air gap and/or wear monitoring
- Manual release lockable
The spring-applied brake is a disc brake which, depending on the version, has two or four friction surfaces. The braking torque is generated by several compression springs by friction locking. The brake is released electromagnetically.
During braking, the rotor, which is axially movable on the hub, is pressed against the friction surface - via the armature plates - by means of the springs. The asbestos-free friction linings ensure a high braking torque with low wear. The braking torque is transmitted between hub and rotor via the splines.
In braked state, there is an air gap "sL" between the stator and the armature plate. To release the brake, the coil of the stator is excited with the DC voltage provided. The magnetic force generated attracts the armature plate towards the stator against the spring force. The rotor is then released and can rotate freely.

AC Tech Drives
Variable Frequency Drives not only provide better regulation of the system (and thereby greater comfort), but save significant energy compared with traditional damper or valve systems. The MCH Series is a variable torque AC Tech Drive for HVAC applications and is available with options such as bypass, line reactor, and input disconnect or circuit breaker. The MCH Series AC Tech drives also include PID
Lenze's single-axis drives combine mains supply, DC bus and inverter in a single drive. The filter elements and the brake chopper are integrated into the servo inverter and permit autonomous use in distributed control cabinet installations. Higher interference levels can be achieved without a larger mounting area by using suitable footprint filters (up to 55 kW). Lenze multi-axis drives are particularly suitable
