Product catalog summary
Overview:
The BM3 motor is a spool valve motor with double ball-bearing support, designed for medium-duty applications. It offers high efficiency and economy, with features that allow for easy control of shaft rotation and speed.

Key Features:
  • Double ball-bearing support allows the shaft to carry larger radial forces compared to the BM2 motor.
  • Reliable shaft seal design can withstand high pressure, suitable for parallel or series use.
  • Easy and smooth control of shaft rotation direction and speed.

Specifications:
  • Displacement options: 100, 160, 200, 250, 315, 400 ml/r.
  • Continuous flow: 58 LPM; Intermittent flow: 68 LPM.
  • Continuous speed range: 140-551 RPM; Intermittent speed range: 162-646 RPM.
  • Continuous pressure range: 9-14 MPa; Intermittent pressure range: 10-17 MPa.
  • Continuous torque range: 178-418 N*m; Intermittent torque range: 216-464 N*m.

Operational Recommendations:
  • Maximum pressure is the allowed pressure at the inlet port.
  • Avoid simultaneous maximum RPM and maximum pressure.
  • Recommended hydraulic oil: Anti-wear type with viscosity 37-73 cSt and filtration ISO18/13.
  • Maximum operating temperature: 80℃.
  • Special shaft seal allows back pressure up to 10 MPa; recommended back pressure is 5 MPa.
  • Case drain line recommended for back pressure above 5 MPa to extend motor life.
  • Run motor at 30% of rated pressure for at least one hour before full load application.

Mounting and Dimensions:
  • Standard rotation direction: Clockwise when A port is pressurized, viewed from the shaft end.
  • Various mounting flange and shaft options available, with specific dimensions and ordering codes provided.

Recommended preferable back pressure 5 Mpa. Case drain line is recommended when back pressure higher than 5 Mpa.. The motor life is benefited from a case drain line. © It is highly recommended that the motor runs at 30% of rated pressure for at least one hour before application of full load. Be sure the motor is filled with fluid prior to any load applications. M8J Ainai, Standard Direction of The Motor Rotation: CW-When A Port pressurized, viewed From the Shaft End.
