About Iron Crane Duty AC Brake Motor

Product Description:
The Iron Crane Duty AC Brake Motor is a powerful and reliable motor specially designed for EOT cranes, hoists, and heavy material handling machinery. It integrates a three-phase AC induction motor with a fail-safe AC electromagnetic brake, providing instant stopping and load-holding capability during power failure or emergency conditions. Built with a rugged cast iron body and 100% copper winding, this motor delivers superior torque, high efficiency, and long operational life in demanding industrial environments.

Built for Rugged Crane and Hoist Operations

Engineered to meet the strenuous demands of cranes, hoists, and material handling equipment, this AC Brake Motor with insulation class F and service factor 1.15 ensures reliable start-stop performance. Its robust cast iron frame provides durability, while heavy-duty construction guarantees maximum longevity even in atmospheric environments with humidity up to 90% RH.

Efficiency, Safety, and Versatility

The motor operates efficiently at 50 Hz, 415 V, and is available in various power ratings and speeds for flexible application. With an advanced electromagnetic AC brake system, it ensures rapid and secure stopping. Its double-sealed ball bearings, low vibration, and optional thermistor safeguard against overheating and wear.

Custom-Matched for Diverse Applications

Available in foot, flange, or face mounting arrangements and customizable dimensions, this motor is suitable for new installations or retrofits. Protection features like TEFC and IP55 rating ensure safety against dust and water ingress, while high starting torque supports heavy loads. Its compatibility with both CW and CCW rotation adds further utility.

FAQs of Iron Crane Duty AC Brake Motor:

Q: How does the Iron Crane Duty AC Brake Motor enhance safety in material handling applications?

A: Equipped with an electromagnetic AC brake, the motor ensures quick and reliable stopping, essential for the safety of crane, hoist, and winch operations. The optional thermistor provides thermal protection, reducing the risk of overheating during prolonged heavy-duty use.

Q: What industries and applications can the Iron Crane Duty AC Brake Motor be used for?

A: This motor is ideal for EOT cranes, hoists, material handling systems, winches, and lifts. Its heavy-duty construction and customization options make it suitable for manufacturing, construction sites, warehouses, and other industrial environments requiring frequent start-stop operations.

Q: When should I choose this motors S4/S5 duty cycle for my equipment?

A: The S4/S5 (Crane Duty) rating is recommended for applications involving frequent starts, stops, or reversals, such as in cranes and hoists. This ensures the motor operates reliably under variable load conditions without overheating or excessive wear.

Q: Where can the motor be installed, and what mounting types are available?

A: The motor offers flexible installation options, including foot, flange, or face mounting. This versatility allows it to be adapted to a broad range of equipment layouts and retrofitted to meet specific site requirements.

Q: What are the benefits of the totally enclosed fan cooled (TEFC) and IP55 rated motor housing?

A: The TEFC design and IP55 rating protect the motor from dust and splash water, extending operational life and ensuring consistent performance even in harsh industrial environments.

Q: How does the high starting torque benefit lifting and hoisting equipment?

A: High starting torque enables the motor to handle heavy loads and initiate movement effortlessly, making it particularly effective for lifting and material handling tasks, especially where frequent stopping and starting are required.

Q: What process should be followed for selecting the right model and customizing dimensions?

A: Selection depends on application requirements such as power rating, mounting type, and size constraints. Dimensions and other parameters can be customized on request; consultation with the manufacturer or supplier is recommended to ensure optimal fit and performance for your equipment.
