MMP BL86-425E-36V GP81 Brushless Gearmotors

Midwest Motion Products BL86-425E-36V GP81 combines a 36 V brushless motor with a planetary gearhead. GP81-007 and GP81-068 provide very different loaded output points, with exact reductions of 6.75:1 and 68.06:1. They require an external motor-control arrangement selected for the actual task.

Review Summary
BL86-425E GP81 is a candidate where either the faster low-ratio point or the slower high-torque point fits the mechanism. Its main selection constraint is the complete torque-speed duty, including gearbox loads and transient protection. Do not interpret the motor name or a peak figure as a complete machine rating.
