Electronic Inverter Low-Noise Concrete Vibrator Shaft
Compare to other type concrete vibrator shaft:
| DC, low noise | Variable frequency motor | Planetary vibrating spear | |
| Operating mode | A in-built brushless DC motor that vibrates by means of eccentric blocks | An in-built variable frequency motor that vibrates by means of eccentric blocks | Planetary vibration via striking of rolling cone in the raceway |
| Power | Powered by lithium cell or safe low-voltage DC source, particularly applied to places in short of power supply | Powered by electric supply after frequency conversion by converter | The electric supply |
| Vibration frequency | DC variable frequency, 200HZ, stable | AC variable frequency, 200HZ, stable | Mechanical beating vibration, 60-150HZ, unstable |
| Noise | Minimum, ≤70db | Low, ≤75db | Loud, ≥95db |
| Effect | Reaching the resonance frequency of concrete; concrete is compact and the surface is highly polished. | concrete is compact and the surface is highly polished. | the effect of vibration is fair. |
| Safety | Safest | ||
| Environmental protection | Meeting the requirements for environmental protection | Producing higher harmonic electromagnetic noise | Producing very loud noise, not environment friendly |
| Operation | Handy and comfortable | Handy and comfortable | The hands of operator will feel numb and tired. |
| Protection function | Electric leakage, overvoltage, overcurrent and overload protections, charge protection, and protection of discharged battery | Electric leakage, overvoltage, overcurrent and overload protections | |
| Other function | Controlled by a single-chip program of microcomputer, up-to date device integration small in size, protection and electric leakage instructions | protection instruction and touch switch | |
| Continuous service life | Long, ≥400h | Long, ≥300h | Short, ≤150h |
| Failure rate & maintenance | Very low, basically needing no maintenance | Very low, basically need no maintenance | High, needing maintenance often |
| Efficiency & energy saving | Maximum efficiency: 88%, the best performance in energy saving | Efficiency : 70%, fair in energy saving | Efficiency ≤30%, No energy saving |
| Cost performance | highest performance and moderate cost | high performance and high cost | poor performance and low cost |
This concrete vibrator shaft have two options:
A. Use with the AC converter(the white terminal box),connect to the main supply power directely.
B. Use the Li-battery as the power source to work.
