| Company Name | AMIT ELECTRICALS |
| Product Name | Crane Duty Two Speed Brake Motor |
| Overview | Manufacturer, exporter, and supplier of Crane Duty Two Speed Brake Motors. Combines three functions: crane duty motor, two-speed motor, and brake motor. Suitable for cranes and hoists in lifting and crane traveling applications. |
| Brake Type | Fail Safe Brake: - Engages when power is off, locking the shaft. - Ensures a precise stop with quick braking action during power supply failure or blackouts. - Provides equal braking torque in both rotational directions. |
| Range of Production | Power: 0.25 to 20 HP (0.18 to 15 KW). Speed Options: 2/4, 2/6, 2/8, 4/6, 4/8, 6/8, 4/12, and 6/12 poles (e.g., 3000/1500, 3000/1000, 1500/750 RPM). |
| Voltage and Frequency | Standard: 415 ± 5%, 50 Hz ± 3% (Combined ± 6%). Custom options for 220V, 380V, 460V, or 525V at 50 or 60 Hz available on request. |
| Mounting Types | Foot (B3) Flange (B5) Face (B14) Foot with Flange (B35) Foot with Face (B34). |
| Frame Material | Rugged cast iron frame with integral feet. Aluminum body available for frames up to 100L upon request. |
| Insulation | Class F insulation (standard) with temperature rise restricted to Class B. Class H available upon request. |
| Protection | Ingress Protection: IP-44 (standard). IP-54 and IP-55 available on request. |
| Duty Cycles | Short time duty (S2) Intermittent periodic duty (S3) Intermittent duty with starting (S4). |
| Shaft | Made from high-carbon steel for exceptional strength, rigidity, and minimized deflection. |
| Rotor | High-pressure E.C. grade aluminum die-cast, dynamically balanced for low vibration and noise. |
| Bearings & Lubrication | Bearings are lubricated with lithium-based grease suitable for temperatures up to 150°C. Supplied with C3 ball bearings, fully charged at assembly. |
| Thermal Overload Protection | Optionally supplied with a T.O.P switch for added safety against overloads. |
| Earthing Terminals | Provided with at least two earthing terminals (one in the terminal box and one on the foot). |
| Paints | Painted with semi-glossy synthetic enamel. Special paint options available upon request. |
| Applications | Ideal for applications requiring different lifting or traveling speeds during upward and downward movement. Suitable for dual-speed gear motors and dual-speed geared brake motors. |
| Features | High torque Noise-free operation High performance and durability Smooth finishing Cost-effective and precision design Perfectly matches application requirements. |
