In conveyors, mills, mixers and pumping units, it matters whether the drive keeps the production line stable under long-term load. H17RL Compact PRO in the H17RL 400X1-4 version is designed precisely for these tasks, where a 1400 rpm electric motor is expected to provide compact output, firm engagement and reserve capacity for operating peaks. VYBO Electric supplies it as a solution for large factories and OEM manufacturers of technological systems who need a reliable electric motor for continuous operation.
Robust cast-iron construction increases resistance to vibration, mechanical stress and fluctuations in operating conditions. This design supports longer bearing life, more precise rotor positioning and stable operation in situations where the asynchronous electric motor is exposed to frequent starts or load changes.
1400 rpm electric motor for stable operation of heavy-duty technologies
Rated speed of 1488 rpm and rated torque of 3594 Nm give the drive characteristics well suited to production processes with both shock and steady loads. For operators of large factories, it is important that the motor helps maintain output even during demanding starting of conveyors, granulators or heat-exchanger systems.
- 560 kW provides sufficient reserve for technological systems with high inertia.
- Rated current △ 400V: 968 A and rated current Y 690V: 561 A make it possible to design the switchboard and protection correctly.
- Starting torque ratio (Tst/Tn): 120 % supports smooth acceleration without unnecessary mechanical overload.
- Breakdown torque ratio (Tmax/Tn): 220 % helps overcome short-term load peaks.
- Starting current ratio (Ist/In): 700 % is taken into account when designing the drive system for starting.
Robust cast-iron construction for long service life
The cast-iron motor body provides the stability needed especially in operations with continuous mechanical stress and higher requirements for mounting rigidity. In technological lines with vibration, dust or thermal cycles, this reduces the risk of unwanted deviations during operation.
Insulation class F and temperature rise B provide room for safe operation in environments where output is not required only for short shifts but for long-term operation. This is also appreciated by those integrating the electric motor into packaging lines, metallurgical units or high-volume pumping stations.
Compact output within a 400 mm frame
The 400 mm frame size provides a favourable ratio between construction dimensions and transmitted power. This is important when reconstructing production lines where the new drive must fit the existing mechanics without extensive changes to foundations, couplings and guarding.
The weight of 3250 kg must be taken into account when designing handling and installation, but it also confirms the heavy-duty design suitable for industrial use with high operating loads.
Efficiency selection for the plant’s energy strategy
The option to choose the efficiency class makes it easier to align the drive with the company’s energy policy and OEM customer requirements. IE3, IE4 and IE5 variants are available in practice, allowing the technology design to be adapted to planned consumption, operating hours and energy-cost targets.
- Efficiency: 96,3 % supports more economical operation during long-term running.
- Power factor: 0,87 helps with power-supply design and network sizing.
- VYBO Electric supplies solutions proven by thousands of satisfied VYBO Electric customers.
Precise rotor mounting and bearings for industrial use
The solid aluminium rotor cage supports reliable torque transfer and stable starting even during repeated starts. 6326C3 bearings on both the DE and NDE sides simplify service planning and increase reliability during long production cycles.
This design is suitable for hammer mills, extruders, rolling sections, high-inertia fans, industrial mixers, raw-material pumping stations, belt conveyors and aggregate crushers. In each of these applications, the motor helps maintain the technological rhythm without unnecessary downtime.
Solution for large factories and OEM integrations
H17RL Compact PRO is suitable for designers who need to combine output, dimensional discipline and predictable servicing in one drive. For large factories it means easier shutdown planning, while for OEM manufacturers it means faster integration into new machines and technological assemblies.
External starting inertia of 367,000 kg·m² and a GD² moment of inertia of 34,000 kg·m² provide input for precise design of starting, braking and coordination with frequency-controlled or direct starting.
If you need a 1400 rpm electric motor for a technological system with high requirements for reliability and installation flexibility, take advantage of the VYBO Electric offer and choose a solution that supports long and stable operation.
