BCY / BCD-bearing precious metal brush permanent magnet DC motor BCY / BCD-permanent magnet motor is to meet market demand and research and development of the micro-motor-bearing products, the project is the state's key projects and new products in Xiamen City focus on technological innovation projects. With the scientific and technological progress, the market for all types of electrical products to small, light requirements, as many electrical appliances in the dynamic components will face higher requirements. At present, almost all the electrical products in the motor bearings are dual-motor, the structural constraints, narrow the volume has been difficult. The BCY / BCD-bearing motors are smaller, look thinner, lighter weight, the same stable and reliable performance. BCY / BCD-permanent magnet motor to the traditional two-bearing motor bold innovation, improve for single-bearings, and bearing a shrinkage technology, optimize the hole with the shaft bearing the gap and to meet with length. Two-bearing to overcome the heart of the problem more difficult to guarantee to ensure the smooth running, low noise. Also reducing the electrical costs and improve the market competitiveness. BCY / BCD permanent magnet DC motor main technical performances of the following table: BCY technical requirements of the standard BCD standard rated voltage current 1.5 VDC 2.0VDC empty ≤ 50 mA ≤ 70 mA no-load speed (3000 ± 300) r / min (2800 ± 350) r / min rated current ≤ 125 mA ≤ 120 mA rated speed (2100 ± 210) r / min (1850 ± 350) r / min starting torque ≥ 0.8 mN? m ≥ 0.7 mN? m starting voltage ≤ 0.8 V ≤ 1.2 V between terminal Resistance (5.2 ± 0.4) Ω (10.1 ± 1) Ω insulation resistance of 1 M Ω 1M Ω through Novelty Search, is still no similar domestic products. Shrinkage bearings used for non-technology related reports. This shows that the motor in the structure of a novelty, a leader in the domestic level.
